Great write-up! I think the 'hybrid model' you mentioned is the only realistic way forward for the Steam launch. Steam’s policy is basically a 'don't touch the wallet' rule, so having the blockchain layer purely for backend ownership while the front-end feels like a standard Web2 RPG is a smart play.
On the rewards side, I’m leaning toward a shift into skill-based incentives. 50% APR is a massive hook for early adopters, but for the game to survive a Steam-level influx of players, the value has to come from the gameplay loop itself, not just the staking contract. Super excited to see how that TON integration looks—managing your Zombie horde via a Telegram mini-app while on the bus sounds like the ultimate 'productive' gaming grind!
