Completely utterly and irreversibly disillusionned. Ironically, I still play 3.5 in one of the greatest campaign I've ever played.
However if we played with ANY system but 3.X, it would be infinitly better. Each session, we are struggling with the rules. Granted, the DM is anal about playing RAW and canon FRCS which could be considered the root of the problem IMO. But that campaign made me realized how much the 3.X ruleset fits only one kind of game. Anything that goes beyond that become a VERY boring strategy game.
I've been a very stong advocate for 3.X since it came out. But since about 2 months, I'm profondly digusted by it. It will be my last D&D ever. I don't know what I'll play next.
For those of you who wonder why I keep playing?
1) the other players don't have the same opinion of the impact of the rules on the game as me. Therefore they don't see the point of changing system since the campaign is (for them) a complete success. The DM, of course, who planned ahead do not want to change system
2) I wanted to quit at some point but part of the enjoyment felt by my friends came by the fact that I played with them. If I quitted, the would quit too and nobody wanted that.
3) I'm not the kind of [insert unsuited word for Eric's grandma] who can't make some compromise. I hate the system, I begin to hate the setting but we can make minor changes that would make me happy enough to keep playing.
What next? I'm sick of d20 in general and overcomplicated systems. I'd like to play in the star wars campaign setting but with a simple system (True20 is still too complicated to my liking!). Probably a homebrew dice pool style.
