I really enjoyed playing Gundam 0079: One Year War. Its like Journey to Jaburo except its alot better graphics and gameplay wise. You go through each episode one by one. Its a basic shooter but still pretty fun to play plus you can switch to your beam sword at any time. You also get to play once as Guntank, Guncannon, and theres a first person shooting level (meh, its alright). There are two levels where you get to use the White Base and shoot enemy mobile suits to. Its only in Japanese, however, so who knows if an American release will come. I got mine from Hongfire so when they get back up, they hopefully might still have it.
