Ogre Battle. I'd love to play a game like that again. I think Unicorn Overlord took some inspiration from it so I'm excited to check that out.
The original Way of the Samurai. It was really cool and unique little game. The sequels never really followed through on the best parts of the first one though unfortunately.
I'd love for there to just be more short games with branching narratives like WotS. Short games that are built to be replayed really spark something off in my brain lol.
I'm surprised with auto battler games having a moment that we haven't gotten any Ogre Battle inspired indies - just Unicorn Overlord. Still haven't played it, but it's on my to-do list.
