Tokyo Japan : Shibuya Kaikan
5 floors jam packed with everything priced at 50yen. Simply the best arcade value in the world for variety and quality. A hardcore gamers paradise for leveling up cheap. They have so many machines it makes you dizzy. Not nearly as many machines as Funspot but obviously a very different selection of games.
Tokyo Japan : Taito Hey
Taito Hey is jammed in between 2 Sega Club arcades in Akihabara. Although it has an amazing selection of all genre's it is a Shmup players dream. One of the floors is nothing but the best shmups with amazing high scores. They even have monitors at the entrance of the building with live play of popular games played at high level. I played Under Defeat there on a massive 37" candy and it was amazing. Even better I went to one of the smaller shops in Akiba and bought it for a fair price 30 minutes later
United States : Sunnyvale Golfland USA
hashiriya1 mentioned it already. This one is a personal favorite as my Street Fighter obsession began here. They were the first place on this continent to get most versions of Street Fighter. John Choi, Alex Valle, even Tomo played there. My friends and I would actually road trip back then just to experience the high level play.
United States : Pinball Hall of Fame
CRTGAMER just posted about this one. Ghetto fabulous. The nicest people and the best pinball selection I have ever seen. The gentleman I spoke with said they have around 600 machines in storage at all times which work well. The only problem they have so many it becomes hard to manage rubber part replacements because they store them so long the rot without even going on the floor!
lastly, I am from Portland and I think Ground Kontrol is just a decent arcade. Maybe its because I've been to all of those places. This may be my last post before I am eaten by hipster babies on bicycles.
