Battle Tech core rules rocked, add ons sucked.
so +1 to tenabrae's opinion, it sounds like considered advice.
I love Battletech. It is a little more involved than GW games, however you do not need to collect 30 or more miniatures to play even a small game, especially for those who play Imperial Guard, or Orks. Battletech needs only 2-4 mechs , vehicles or battle armour squads, and you can play a nice 1-2 hour game.
However you might want to look at some of the new board games out there. There was a game called Shogun, that has been reboxed and sold under a new title., as well as the WWII versions from the same manufacturer. I think one is called "war in the pacific"?
Alternately if it is pure tactics and based on a simple set of gaming rules, try the DBA/DBR/DBM series set in 16mm scale. Board sizes are smaller and the games are just as fun, have simpler rules, and look like GW's Warmaster game which came out much later.
I have not gotten into the space fleet battle type of games myself, so I can not comment on any of them.
