Really enjoying Dodecadragons and how it handles prestiges. Earlier resources become automated, and while there's still some grinding it's not forever and you know that there's going to be a milestone that takes the pain away. Each resource builds, and you know what your target is for the next prestige. I like it.
Louigi Verona's Machinery, I liked the way different prestige mechanics still mean the game is still more or less the same time between resets with more progress, and adding new mechanics.
CheckBackMod - spending prestige currency for more gainz, carefully! It's entirely possible to go backwards because RNJesus isn't on your side!
