yep. pretty much. I'm often wondering how it is that AoC has lived on so long while other RTS, even made after AoC have not. Of course it's all amazingly polished and well balanced etc. but there's also many small details which may seem unimportant but add up to create music. https://www.youtube.com/watch?v=qdVZFF-XC_Q I think the treb is one such detail. The treb castle war fare is often the climax of a game. You spend 30 minutes building your pretty city and advancing your tech.. and then it can climatise when a couple of trebs are pounding a castle while the other guy is still a few seconds short being able to up into imperial... and may be helpless in the time being. It's the equivalent of a goal in soccer.
