hi Fist,

You should start by joining up steamgroups as there is no foyer (there is a pinned thread here on groups).
Then finding a populated server. There are many servers and some has only a few folks on it so you won't see too many games.
Finally by realising that there are only four (well, five) cost efficient unit in the game: riflemen, guards, dragoons, sikh warriors, and mortars. The first three makes a good RPS, the fourth gives the usual inf heavy rush option (think of the byzantine rush) and finally the fifth gives something to ban.
