An updated MoM or MoM2 would be cool.
It's interesting to me that a lot of the gaming industry these days consists of copying successful games, yet there are so very few Diablo II clones (that don't suck) and many incredible games from systems/OSes past have never been redone for current OSes and hardware.
The type of game I'd most like to see Stardock (or a company with similar production and quality values, which is rare) do would be a squad-level tactical game like XCom/JA/SS.
The UFO series is pretty close to XCOM, except that the AI is pitiful, they use starforce, and their followup support (patches, dev interaction) is nearly nonexistent. The company that does the UFO series is like the anti-Stardock.
If you're an old XCOM fanatic (like me) the 2nd UFO game (UFO: Aftershock) is worth playing despite all the issues (if you can stomach dealing with starforce).
All they need to do is ditch starforce, patch their game, and enhance the AI to more than pursue / run and the UFO series would be better than XCOM. The UFO combat system is pretty sweet, the character development system and gear is great, etc. Unfortunately the ultra simplistic/nonexistent AI, ultra crappy load times and general performance, other glitches, and the use of starforce crush an otherwise potentially excellent game.
Somehow, despite all this nonsense, a 3rd iteration of the UFO series is in development. From what I've read of it they're ruining some of the core gameplay that was perfect in the 2nd iteration and since their track record is already tainted I can't see the 3rd game being of any better quality.
Silent Storm is a decent squad based tactical game but again - it has horrendous AI and the followup support was terrible/nonexistent.
I never could get intot he Commandoes series since there was a lot less flexibility in how you developed the characters or executed the missions.
There simply are not enough squad-level tactical games made.
