Try CS:GO. A useful and very often under-provisioned role in public games is that of the 'entry man.' Basically your job is to get out as far as you can, spot the enemy positions, and do as much damage as you can. Its your team behind you's job to tack on kills based on the space you made.

No one really wants to go out first because you usually die first, and have the least opportunity to get kills if evenly matched skill-wise with the opponents. It also takes the ability to 'just go' when the time is right (when the smokes are set or when everyone is close enough to go together or when a distraction happens elsewhere) even if you don't feel fully ready - waiting too long means the enemies prepare better.

All of that will put you in situations where you have the obvious choice of waiting around, or leading the way, and though they rarely do it, its usually better for worse players to go out first so its no problem being new to the game and trying that play-style.
