one thing i love about this system is the endless supply of vintage shooters.
as i get older, i find myself less willing to sit down and make the time investment to play an RPG and shooting games are great for mindless fun.
i recently purchased and have been playing a lot of Areo Blasters, Dead Moon, Psychosis, Cyber-Core and Monster Lair. I'd recommend Area Blasters and Dead Moon as well as Monster Lair if you're looking for more of an action game.
i love the part at the beginning of areo blasters where you're cruizing along over a nice, blue Earth and the aliens nuke everything.
