Well hot damn. I've beaten a fair amount of the beat-em-ups that I have, but there are still a number I could work on finishing. I guess since I have Streets of Rage on my summer challenge list, that's an obvious place to start. I have the two TMNT beat-um-ups on the NES that I could play. I could finally give Golden Axe III more than a passing glance, for once, even though I've never played Golden Axe II. I know I've beaten The King of Dragons on the Capcom Classics Collection, but I think there might be one or two others on those that I haven't beaten. I've also put a lot of time into Tenchi o Kurau II in the past, and could try to actually beat it again, even though the final stage is a freaking death-pit, and the limited continues make that a really tough task.
Just some thoughts for others who might be emulating with MAME: Don't neglect the Konami library. There's a bunch of (probably) quality games that weren't ported to consoles, like Bucky O'Hare, Metamorphic Force, Asterix, Violent Storm, Vendetta (I played this one a bit back in the day), and of course the classics like Simpsons Arcade, and X-men. Crime Fighters, anyone? (I may have been one of the only people playing this game in the arcades--.) Capcom still pretty much has a lock on the arcade beat-em-up scene, though, with AvP, Armored Warriors, Battle Circuit, Cadillacs and Dinosaurs, Captain Commando, and the D&Ds. Two final thoughts: Someone has to play Ninja Baseball Bat Man, right? Also, I don't know if it's actually good or not, but the Spider-Man arcade game from Sega was one I used to love when I was a kid.
Noise, I think I'm as befuddled as Bone is. I can kind of get not liking Guardian Heroes, with it not being too immediately approachable, but I don't see how anyone could not enjoy the D&D arcade games. If this isn't one of the greatest characters in human history, I don't know what is:
I mean, she's like Little Red Riding Hood, if instead of relying on the hunter, she just surgically extracted her grandmother while the Wolf drones on about his big eyes making it all the better to see her with; and kept his pancreas as a souvenir; Then flayed his pelt, and hocked it to fund more daggers.
