It is if you use PCSX2.
This is my personal favourite list:
SVR2006
HCTP
SYM
SVR2010
SVR2006 was the ultimate release in my opinion. The only two things that I don't like about that game are the standard backflip counters that even Andre The Giant would do and the sleeper mini game that was way too hard.
SVR2010 is basically on my list because that was when we really started the modding community that lives to this day.
I spent so much time programming svredit for 2010 - in the end it had support for all versions of 2010, PSP, PS2, 360 and PS3 - (and that actually resulted in kind of burning out my WWE modding interest), but it really got the WWE game modding off the floor.
It's so cool to see how the games (also the new ones) are all modded to this day and how we can transfer wrestlers between games. This was something I wanted to do since the early Smackdown days, as an old fire Pro, NHL and PES fan where the editing capabilities had always been better.
The work done by brienj on the mod that started it all, SVR2010 2.0, Tekken57 with the PAC editor, everyone researching and sharing info on how to mod the game, the thread we had on caws.ws... That was when the doors were opened for all the WWE modding we can see today on youtube. It was a really cool thing and time to be a part of.
