Oblivion used particle (sprite) trees and we used them some in The Dark Mod too (Doom3 Thief total conversion).
They can look really good as they give a tree top a very round bushy look that is hard to do without tons on planes.
They can look pretty bad too, as the particles always face the player. If you stand really close, look at the leaves and spin your view, the leaves spin with you. Kaliedescope effect. I still think the look pretty good overall, it's just discerning mostly while screwing around spinning looking right at the leaves.

I've gotten to the point where I just prefer to clone the leaf planes and flip normals and combine them with the model.
That's what nocull does anyway. But using nocull gives you an 'artificial' tri count. You see 1400 tris in 3d program, but in game it's really 2400 tris. If you just build them yourself you know exactly what you have.
