Here are some favorites of mine that I've found at Armor Games. Some of the games there are good, some are awful. Either way, these proved slightly addicting. Not earth-shattering by any stretch, but still fun. Some of them feature multiple-play benefits, saving games, etc.
I second your opinions on Straw Hat Samurai, Warfare - 1917 (damn that last level), and the Last Stand games. I'll be playing the others in a minute. Also, have you played the Fancy Pants Adventure games?
You Have to Burn the Ropeis good. But you probably won't find yourself spending a lot of time playing it, since it's... well, it is what it is.
What the hell are you talking about? It took me two hours just to figure out what I was supposed to do. And even then, the levels are a bitch. The end guy was really tough.
