Right, its a turn-based tactical wargame. It's not a sim, it's not real-time. However, it does a fairly good job at 'simulating' the behavior of many modern weapons (MBTs, ATGMs, RPGs, arty, helos...).
I remember the huge research the old spcamo team did during the DOS SPMBT times to gather correct data on the units present in the OOB (database).

I paid only EUR 93 for SBP PE, including shipping and taxes. After all, in Euro countries it's only 1.5 the price of a console game.

From the little I have tested, it's well worth one and a half game. :D

Damn, I should remember that 125 refers to dollars, not euros. I too payed only 97 euros one year ago, I think.
