Battle Forces is similar, but a stripped down version (i.e. same units but no technology development or strategic air raid, just combat). No download required and you can play up to 3 games at once with a basic membership for free.
If it is a real board game you’re looking for, then Eclipse and her extension : you can play up to 9 players, and it’s really fun. With 9 peoples, it could take up to 5-6 hours to complete the game though.
I thought it might be a game called Stargate. I played a game called Vector 3 by the same company long ago. I’d love to get my hands on one of those now. I think I bought it for about $5 back in the early 80s.
Just refreshing this thread
I’m big on Strat games
At the moment am playing Age Of Empires 3 again after a layoff of well over a year, forgot how enjoyable that game is
Also play but not so much any more
C&C Generals
Age of Mythology
Dawn of War.
