The main thing to me is that people respect your raises more the higher you move up in levels. In low levels, it does no good to limp in the early levels. At the higher buyins, I will limp in late position with most hands in an unraised pot with several limpers. It is much easier to steal a pot here. Positional raises after one or two limpers, which don't work at lower limits, can also work quite well at the $100 and $200 level.

One notable thing is that people at lower levels will almost never check their top pair --- but at the higher levels they will often treat their top pair weak kicker as a bluff catcher --- they don't bet it but they call your bet. If I do a position raise, get checked into on the flop, and then bet with nothing, if I get called, I shut down for the rest of the hand. At lower levels you can pick it up on the turn, but not at the higher levels.
