Yeah, old TT had games like that too. Most were short, and some went crazy long, which was just fine with me, since I would be Nasus top with a crazy farmed Q, so I could just about dive and tank towers. My favorite TT game ever was probably a game where everybody was at full build, and I took Tristana over the wall to smash the nexus before anybody could do anything about it.
My two games so far have been one where my laptop couldn't handle the settings, so I looked stupid and died a lot (it wasn't just my computer, I was fairly bad that game), and the second game was kind of back and forth at first, then kind of stalled when we each had an outer tower, and then we had one good fight at the inhibitor tower, aced them, and then just about had the nexus down before the opponents respawned.
