I started replaying God Hand this week for the fourth time. Its gameplay is so good that I've never felt it has aged. The movement while turning (not the quick turn) takes a while to get used to, but I don't know how it could really be improved on in the modern era except that playing on a wider-screen would make turning feel less rapid, which would be nice, especially in the clostrophobic indoor areas, which is where Godhand's perspective hurts it the most.
Fighting is just so satisfying. The game of trying to guess when the enemy is going to guard, breaking the guard, dodging, using attacks to dodge or juggle--it's all very close to perfection. The absurd humor still cracks me up. It never gets old spanking people and sending them flying with that one final slap.
If I remade the game today, I'd probably take out the casino, and all the moves would be found as random loot drops or earned through a skill tree/talent system.
I'd like it if there were more themed movesets
based on real martial arts, like the drunken fist moves.
