As you probably already know, Champions Online and Warhammer Online (among others) employ level-restricted trials, allowing players unlimited time, but not unlimited access to the world. By contrast, Alganon isn't limiting people on the trial to a specific level. Indeed -- players can level as high up as they can, to the game's current cap. The catch is that at 30 days, your character starts pining for the fjords and is deleted if you don't convert that trial over to a paid account. If you level very fast and don't mind the idea of having to reroll once a month, this could be an interesting way to explore the content in Alganon for some time without paying anything. That said, there are other drawbacks to dissuade players from doing that; limitations on crafting; inability to freely chat; only able to take skills to level 3 among others. Overall we still think this is an interesting new tactic for an MMO trial system.
