I'm still playing Tactics Ogre, which I bought full price on PSN, and which now has been reduced by 50%, pissing me off no end. No PSP game really has any business being sold for that much. Still, it's an interesting game in its own way, although there are little things here and there which make me just want to turn it off and play Advance Wars instead. It's rather slow paced, and tactical considerations can't take into account the movement and attack ranges of enemy units, which means you are really reacting to whatever they do rather than being able to pre-empt any of their prospective moves.
The story is really rather good for a JRPG in all honesty, which I wasn't expecting. It's still full of all manner of ye olde world speak, but nothing that encroaches on being absolutely embarrassing tbh.
Other than that, really looking forward to the Wipeout dlc.
