@TIM: Of all the non-vanilla launchers for Minecraft I've used, the only two I'd consider truly "professional" would be MultiMC and Feed The Beast. No unimportant visual fluff where it didn't belong. Simple, easy-to-understand UI, and logs that were (at least for FTB, dunno if it was so for MultiMC) on by default. I like logs for things like that, it lets me know just what's going on, and many times, just what's going wrong.
@Zack: Aye, a fair example of a bad Dragon Ball game would be Battle of Z's predecessor, Ultimate Tenkaichi. The latter played more like Dance Dance Revolution than an actual fighting game, much less feeling like Dragon Ball Z. Make no mistakes, Battle of Z is hard. It is fucking insanely hard, at certain points. However, its not hard because of shitty controls or the computer being completely unfair, its legitimately challenging and for that, I love it.
