Players of the MMO Champions Online should be familiar with the game’s tutorial: Saving the city from the alien invasion. Starting today, players have an unlimited amount of time in that section of the game before they have to buy it. Level yourself up to the demo limit of 15 and see how you enjoy the scenery. You are limited to two character slots, and it appears you’ll need Steam for the demo. Check it out here.
I’d like to point out that Cryptic isn’t using a tactic like Mythic and Funcom did in Warhammer Online and Age of Conan respectively, in regards to the limitless trials. In those two games, they took the (according to players) most fun part of the game, and made them free. At least with Champions Online, you’re not seeing the best the game has to offer, suckering you into buying the title, followed by immediate disappointment when you realize that you just bought a house based on the mailbox and the garage door, to find the rest of the building had been burned down in a fire.
Champions Online is a fun game that truly deserves at least a try. Now that the limitless demo is here, there’s no reason not to download it.

I totally agree with you. Everybody who likes MMOGs and comic heroes should give the Champions Online demo a try.
