Victorious Boxers 2: Fighting Spirit (PS2), cheap-looking Ippo boxing game. brother's a fan of the manga and it was basically free at EB
Metal Gear Solid / Ghost Babel (GBC) Non-canon, but it looks like a sequel to Metal Gear 2: Solid Snake
Disgaea D2: A Brighter Darkness (PS3) Disgaea is a huge timesink so I skipped #4, but now that we're finally back with characters that started the series off I'm interested again. And technologically, the series just get better with every new entry since they keep piling features on to make grinding more fun.
