There are several Play-to-Earn (P2E) games similar to Axie Infinity and Gods Unchained that offer opportunities for players to earn cryptocurrency or in-game assets while engaging with blockchain-based gaming systems. Below is a review and guide for some popular games in the P2E space, including Axie Infinity, Gods Unchained, and others:

1. Axie Infinity

• Overview:
  Axie Infinity is one of the most well-known P2E games, where players collect and battle creatures called Axies. Axies are NFTs (non-fungible tokens) that can be bought, sold, and bred. Players can earn Smooth Love Potion (SLP) tokens, which can be exchanged for cryptocurrencies like Ethereum or used for breeding Axies.

• Pros:

• Earnable Tokens: Players can earn SLP by participating in battles and completing daily quests, which can be exchanged for real money.

• Engaging Gameplay: The gameplay is similar to a turn-based card battle game, requiring strategy, skill, and a good understanding of Axie traits.

• Community and Ecosystem: Axie Infinity has a large, active community, which  includes scholars, managers, and breeders.

• Cons:

• Initial Investment: Axie Infinity requires an upfront investment in Axies       (usually 3 Axies), which can be expensive, especially for beginners.

• Economic Volatility: The value of Axie-related tokens and assets can fluctuate  significantly, leading to uncertain earnings.

• Game Sustainability: The in-game economy relies on continuous new players and high demand for Axies, which could impact long-term stability.

• Tips:

• Start with a scholarship program if you don't have the initial capital to buy Axies. This allows you to earn without upfront costs.

• Focus on improving your team by carefully selecting Axies with strong attributes for battles, rather than focusing only on the breeding process.

2. Gods Unchained

• Overview:
  Gods Unchained is a blockchain-based collectible card game similar to    Hearthstone. Players collect cards, build decks, and battle other players. Each card is an NFT, and the game uses GODS (the native token) for transactions.

• Pros:

• Free-to-Play Entry: Unlike many other P2E games, Gods Unchained allows players to start for free by earning starter packs and cards through gameplay.

• Strategic Depth: The game offers a high level of strategic depth, with players  needing to carefully build decks and anticipate opponents’ moves.

• Play-to-Earn Potential: Players can earn valuable cards by winning matches, which can be sold on the marketplace for cryptocurrency.

• Cons:

• Steep Learning Curve: For new players, understanding card synergies and       strategies can take time, especially when starting without knowledge of       collectible card games.

• In-Game Economy: The value of cards can fluctuate, and selling cards requires finding buyers in the marketplace, which can sometimes be difficult.

• Tips:

• Learn the mechanics through the free starter decks and beginner guides before investing in rare cards.

• Participate in ranked matches and events to increase your card collection and earn rewards.

3. Splinterlands

• Overview:
  Splinterlands is another popular blockchain-based collectible card game where players battle with cards that represent different creatures and abilities. Players earn DEC (Dark Energy Crystals), which is the in-game currency, by winning battles.

• Pros:

• Free-to-Play Options: Like Gods Unchained, Splinterlands offers free-to-play options, allowing players to start with a limited collection and earn more cards as they play.

• Quick  Matches: Games are relatively fast, making it more accessible for players who may not have hours to invest in long gaming sessions.

• Earnable Tokens: Players can earn DEC and other in-game rewards, which can be traded or sold in the marketplace.

• Cons:

• Initial Investment: To unlock some of the more advanced features and higher  earnings, players may need to purchase cards or a summoner's spellbook.

• Card Market Complexity: The card marketplace can be competitive, and finding value in certain cards can be challenging.

• Tips:

• Start with a spellbook purchase to unlock all gameplay modes and start earning DEC.

• Build a balanced deck by focusing on upgrading your cards and using them    strategically to maximize your chances in ranked play.

4. The Sandbox

• Overview:
  The Sandbox is a virtual world where players can create, buy, sell, and play on virtual land and assets. It’s part of the larger metaverse ecosystem, and in-game assets (such as land, avatars, and items) are represented as NFTs. Players can earn SAND, the native token, through various activities like creating virtual worlds, playing games, and trading assets.

• Pros:

• Creative Freedom: The game offers a high level of creativity, allowing players to design and build their own worlds and experiences.

• Real Estate and Asset Investment: Virtual land in The Sandbox has become highly valuable, with players buying and selling land for substantial returns.

• Strong Ecosystem: The Sandbox has partnerships with major brands and artists, enhancing the game’s credibility and long-term potential.

• Cons:

• Entry Cost for Landowners: Buying land in the game can be expensive, especially in prime locations, limiting access for beginners.

• Learning Curve for Creation Tools: The tools for designing and creating assets  require a learning curve, which may not be appealing to all players.

• Tips:

• Start with small investments if you’re new to virtual real estate and focus on    creating valuable assets.

• Engage with the community and explore user-generated content to get inspiration and learn how to monetize assets in the game.

Conclusion

Each of these P2E games offers unique opportunities and challenges, but they all share a common thread of using blockchain technology to allow players to earn through in-game activities. When selecting a game to invest time or money into, consider the following:
