I finished Rushing Beat Ran again. The flaws become more apparent when going back to the game. It's still a decent brawler, but it needed more enemy variety. There's only 4 stages, but those stages get longer the further you go into the game. Especially by the final stage. Never bother with Normal nor Hard mode, because all it does is spawn in more enemies. You can only fight 3 enemies at a time in most SNES brawler games, and that just pads the game. Streets of Rage 2 was made on a console with much weaker hardware, yet has more levels, better graphics (not from a lack of trying on RBR's part), and much better enemy variety.
I prefer playing as the speedier characters like Rick, Wendy, and Kazan. Due to how cheap certain enemies types are, the slower and larger playable characters are just bigger walking and easier targets. So they're strength is not even worth it, and when the other three characters can do the same at a faster rate. I prefer Wendy especially, because how fast she is, and has the high damaging wrestling moves to dish them out. She is a female pro wrestler after all. I am glad they brought her back for the upcoming sequel. I am going to play her first, if she's available from the start.
I will get back into Sonic Generations at some point.
