Mythos shows the most creativity in its classes. Your characters must choose between one of three classes, but the talent trees can turn them into almost any variant on those you can think of. Want your caster to tank and melee? You can do that. Want your gadgeteer to let his pets do the fighting? Entirely up to you. Your character can be uniquely yours in every respect. This might come in handy when you meet someone else in the FFA PvP world of the Shadowlands. They won't have any idea what you can do... and you won't know anything about them, either. Will Mythos have the staying power of Diablo II? That's a tough call, but the developers at Flagship Studios are definitely hoping its addictive gameplay, casual setting, humor, and low price (can't beat free) will give them a hit after their miss with Hellgate: London.
