Lotta love for Henry Hatsworth and Infinite Space makes me really happy.
To add one of my one, Avalon Code was an interesting RPG that tries to do its own thing with its book mechanic, where you basically smack everyone and everything with it to make a magical compendium. It gives you the usual stats/info etc, but lets you modify things within it too based on a number of parameters. You can do nasic stuff like upgrading weapons, but also changing personalities of people or monster stats to solve quests or make things easier or harder for you.
It's a solid 7/10 game otherwise, but nice that it tried something to stand on its own two feet.
