Everyone's got a couple of these, but please, try to keep it to just one game. Also, if you post in this threat you should try to investigate a game or two that others have posted, because really, that's the point.

For me, it's Aquaria. This video says it better than I could:

There are a load of games better than The Maw and Watchmen... not sure what you already have, but consider some of these if you don't have 'em:

Bionic Commando Rearmed
Castle Crashers
Braid
Geometry Wars 1 and 2
Prince of Persia Classic
Pac Man C.E.
Mega Man 9
Poker Smash
Uno and Uno Rush
Alien Hominid HD
Banjo Kazooie, Banjo Tooie

That's just my opinion, though.

Plants vs. Zombies.

I'm nearing the end of my first play through on hard and I'd say it's about an 8.0. I'm still having lots of fun with it, though, and looking forwards to replaying it on Commando.

That would be amazing, but probably too amazing for the PSN. Lately, I've stopped expecting anything from the Playstation Network  =(

Sandman is very tough, and that first attack that he throws is just so insanely fast. I beat him a couple of nights though, and yeah, the second play through is much, much harder than the first.
