Okay, I took the plunge and got Crazy Strike Bowling... Here's the verdict:
-Yes, pretty much Wii Sports bowling with anime characters (yes, some of which have boobs...lol)...
-Pretty simple to pick up and play (although it has an acceleration gauge and I'm still not entirely sure if it relates to your actual throw or is separate since I threw a few normal balls that totally crawled)
-Online and local multiplayer (and facebook connection if you're into that kind of thing)
-The Challenges add some extra single player content and are sort of fun from what I checked out of them (things along the lines of "score this many points in 90 seconds" or "make this shot" or "get 2 spares in 3 frames"...and looks like there's some trick shot stuff I haven't unlocked yet where you have to dodge obstacles...)
-Load times are bizarrely long (not a big deal if you're playing a whole bowling game, but it gets annoying quick if you're doing a 20 second challenge and have to wait through 15 or 20 seconds of loading/saving every time you fail and retry)
-Had calibration issues at first (kept failing when I held the controller up to my shoulder), but it might have been due to having a dualshock on and set as controller 1. After I quit the game and turned off the dualshock and restarted, I think it only failed once.
-Physics seem simpler than Wii Sports (throwing right down the middle here is the key to a strike)
-Controls don't seem as sharp/complex as Wii Sports
Overall, it's pretty basic...but fun enough. Maybe worth the $2.40, depending on what you're looking to get out of it. There's a bunch of DLC, but it looks like it's mostly to unlock stuff you can get from playing the game and doing challenges. There does appear to be an extra 99 cent Halloween lane and costume DLC if anyone's looking for some Halloween themed bowling for October and that sways you.
