I think he's referring to Steel Beasts Pro...indeed a very nice simulator, but lacks a campaign that was used in M1TP2. Not that a campaign lacking in Steel Beasts Pro is a criticism, as there are hundreds of single and multiplayer scenarios available to download.
That's correct I play SB now its a far better simulator then M1 but M1 will always have a special place on my top ten games /sims of all time.
