I actually prefer Mai's costume in Fatal Fury 2, 3, Special, and Real Bout sub-series. Her costumes started out as conservative, even for the time. The fan-service mainly came from her bouncing chest, and some times going bare feet/toe-less socks (though that part is less fan-service, unless you already have a fetish for that kind of thing). It wasn't until Fatal Fury: The Motion Picture and KOF '96 that she got more stripperiffic and ditzy. I don't mind the fan-service, but it's still annoying how many SNK fans misremember how she started, or people outside the spectrum just assume Mai was "always like that".
Oneechanbara: Bikini Zombie Slayers is a decent game. It's not a 1/5 or 3/10 a lot of reviewers were making the game out to be. BZS is a 3/5 type game. There are good and hidden mechanics, if one bothers to actually play the game, and not rush out their review for quick rant gag, or because they're on a dead line. It's a budget game, so there are going to be problems. The environments are samey with nothing special, you're essentially going through the same levels 4 times total when you unlock all the characters, unlocking costumes is a disaster without looking up GameFAQs, and controls are Wiimote and Nun-chuck only. Surprisingly, the motion controls work and has an almost rhythm to how you do the moves, but Classic/GC control would have been nice alternatives for those that want it, or have certain handicaps. Every character either has two weapons or two stances, they all play completely differently, each have a taunt, and while the enemies are mostly weak sauce, they definitely put up a fight on harder difficulties. This game ain't DMC1, 3, 4, nor 5, but is better than DMC2 and Chaos Legion.
I would not have paid $30 for it though. $20 would have been okay for me, had D3 started at that price. I got this game for $5 back in 2017. A few years prior, the game was sold used $1-2. Today, the game is a bit more pricey, but you should be paying no more than $15-20. Anymore than that, then do not bother, and play the games on PS4. As far as 3D brawlers (there's not that many) goes on the Wii, you can definitely do worse. It's not Mad World, nor No More Heroes, but BZS is better than Red Steel, Samurai Warriors 3, or Spyborgs. Funny enough, there is this one user reviewer on GameFAQs that considered NMH and MW to be pieces of shit, and considered BZS to be the best 3D brawler on Wii. The person was known for being contrarian and vindictive. I like the game, but that is just not true.
