If anyone is looking for a fun Gundam game to play online I highly suggest checking out SD Gundam: Operations:
Its a free to play Yahoo.jp (Japan,obviously) browser game. All you need is a Yahoo Japan email address, which is easy enough to create. You can create one by going here – http://www.yahoo.co.jp/and clicking on the mail icon near the middle of the page. It helps to have a basic understanding of Japanese, but you can certainly work your way through it.
The game is a fun mixture of strategy, customizable card game and “gatchapon” collection. You just need a mouse to play and the battle interface is similar to most SD Gundam games.
There’s a great tutorial to walk you through the basics.
If anyone needs a guide to setting up an account, let me know, I can work on one.
Careful, it’s addicting!
