Although Titan Quest is an RPG, the character set-up and development is pretty straightforward so that you can stay focused on the action. Eight different "mini-classes" are available, and whenever you create a character you pick two. So, you can be a warrior who uses fire magic, or a healer who uses pets, or any combination you want. Each of your skills can be leveled up, and the developers have taken care to make sure that it's impossible to level up any skills that would become obsolete before end of the game. By way of demonstration we were shown how a first level fireball skill can be visibly improved by upping your fire-magic skill, and then how it can be made even more useful by adding fragmentation at higher levels (the fireball split into several others on impact.)
