Tactician might be the right word.

In on-line FPS I'm all about the objectives. For example, I always carry smoke grenades when I play CoD with my roommate and I can easily resist chasing enemies I don't need to kill if that means getting to the objective quicker.

In RPG's stuff gets varied. I plan a lot nonetheless, and I tend to be melee based because it usually just feels more intense than a back-row mage. It heavily depends on the kind of RPG, but mostly I stop and think up a strategy rather than a trial and error or grindy approach.
