Bowl-mani fest is both a Bemani, and Bowling (since TGA is located in a small ten-pin bowling alley) festival. Look at
Tokyo Game Action for information on the arcade itself. This will give you a good idea of the games that TGA has at the moment. It doesn't give prices, even though last year during the festival it was $25 per day for Free Play for games (no pay per play) and concerts. I don't know how much the Tournaments were since I didn't and probably still won't enter.
There are a lot more games now than there were last year, which is good, since that game room got really crowded, and smelled a little funky on Saturday (Kors K concert, which was the headliner). Last year there were consoles set up in a small room between the music game room, and the (now) fighting game room.
TGA is in the middle of nowhere Massachusetts (Winchendon). It's about 10 minutes from New Hampshire (Rindge). There's a mountain for hiking (Mt. Monadnock) close by, and sky diving (in Orange, MA). Other than that there's nothing. The closest mall (or society) is 20-30 minutes from there.
I'm sorry if this seems like a lot of info, but it's necessary. It is the only arcade that I go to now (Friday's

), and the atmosphere is nothing short of amazing. It really is worth a trip up here, during Bowl-mani fest or even before.
