Well, it's a bit more than the "Minis" games, sure the game isn't some epic adventure across time and space, but it's a very good game though. Thing is, it's £23.99 on the Playstation Store, I bought on preorder from GamePlay for £21, and now it's reduced to £17.99. Trust me though, if you want a quick fire sim/tactics games, this is one to get.
As a commuter game, it defiently isn't slow paced if that's what you want. The only problem you might find with it is that in the main story mode, there's no way to save game, so if you get far in the story, and have to leave the train, the only way to keep progress is to put the PSP on sleep, kinda annoying. Thing is though, the more you progress into the game, the more challenge modes and tutorials you unlock, that are simply 5 minute rounds that are perfect for pick up and play time on the train.
