I've been playing Ogre Battle: March of the Black Queen on my Wii, and it's a pretty fun game if a bit long winded. My only beef with it, is that it is definetly one of those games where the Manual was actually important in explaining background information and certain rules about alignment and classes. It's still a really fun game that comes across very simple but looking through guides you begin to realize how deep the rabbit hole really goes.

I actually own Tactics Ogre: Let Us Cling Together for the PSP but have yet to get around to it since I'm still juggling a second playthrough of a few games, and my first playthroughs of P3P and MGS:Peace Walker, so it's in the back burners for the moment.
