Glad to be of service.

As far as the others go, it depends on your tastes.
Generations 1:
*1942
*1943
*1943 Kai
I don't believe I've played this one, but I plan on getting ahold of it at some point.
Generations 3:
* Vulgus
* SonSon
* Pirate Ship Higemaru
* Exed Exes
Another that I haven't played, but I'm not really on the lookout.
Generations 4:
* Commando
* Gun.Smoke
* Mercs
I've got the Playstation version of this, and it's great, especially since I don't do laundry at the laundromat anymore. I've loved Commando since I was a kid. Gun.Smoke was awkward, since I had only played the NES version growing up. You go from the 2-button setup of the NES version to a 3-button scheme that gives you more firing options. The game is just begging the use of a dual-joystick setup.
Generations 5:
* Street Fighter II
* Street Fighter II': Champion Edition
* Street Fighter II' Turbo: Hyper Fighting
I didn't know that this had gotten a Saturn release. It's the only Generations title that made it to the U.S. (Europe got 1-4, don't know about 5) It was released here on Playstation as Street Fighter Collection 2. If you're a fan of the first 3 versions of SF2, it's great. I think the load times were better than the original Street Fighter Collection, but don't quote me on that. Saturn probably has better load times. Besides everything else you can expect from Street Fighter (outside of load time, I think it may be arcade accurate), there's an art gallery per title and the option of using a remixed soundtrack.
