Senjou no Kizuna is a great game for any hardcore Gundam fan, but requires a bit of dedication upfront. As a port of an arcade game, the PSP could never replicate the original twin-stick controls, but the adapted control scheme works well once you're used to it. While it's still based around short arcade-like rounds, this is much more simulation than pure arcade action---unlike other Gundam games on PSP like the VS series (Gundam vs. Gundam, Rengou vs. ZAFT, etc.), this is a very methodical game which requires patience and proper timing to succeed. The controls aren't particularly intuitive (the manual provides no help in this regard), but luckily the game has a Mission Mode that provides perfect tutorials for all of the game's mechanics. Even non-Japanese speakers are in luck, because the tutorials show button presses on screen as they walk you through, so it's just a matter of repeating what they demonstrate.
