A few years ago (actually, probably 10 or so) I was reading with great interest about a game in development called “Guardians: Agents of Justice” or something like that. It was to be a turn-based, isometric, squad-scale combat game…essentially X-Com.
With superheroes. And highly customizable powers, based partially on the Champions RPG system. And fully destructible environments. And a massive, non-linear campaign in which your group would work against a wide variety of supervillains and evil groups.
And then it eventually fell out of developement. Want! WANT!
Having thought about it, I would love to see a new Syndicate game. Unfortunately, Peter Molyneux is now at Microsoft Game Studios, and the Syndicate franchise is owned by EA (I think), so it will probably never happen.
although it doesn’t really meet all of your criteria, have you played Crackdown?
As for my own contribution to this thread, take Dwarf Fortress, combine it with some of the mechanics from Theme Hospital, and put it all in a modern engine. Instant classic.
I want a version of EverQuest re-tuned to be a single player game. Sort of a cross between the original EQ and Oblivion. Yeah, and let us play online with buddies.
Make it a PS3 exclusive and I’ll have a PS3 by the end of the week.
Sounds like a much larger version of Battlefield 2142.
Technical limitations not withstanding, I would like to see a gigantic, strategic scale version of a Battlefield series type game. Basically a much larger map with many more players. Much in the same way that BF2 had a Commander and Squad Leaders to encourage random players to work together, it should have a similar setup (but with more levels - squad, platoon, company, battalion). Fewer objective flags and they wouldn’t be spawn points. You would have to spawn at either some depot behind the lines and make your way to the front (or maybe paradropped or helicoptered in to your company commander’s position). That way, the battles would be more like the way actually battles are fought - with cohesive units attempting to outflank and cut each other off instead of dudes just materializing on top of flags.
And for shits and giggles throw in some AI civilians as well. They start out neutral, but as collateral damage increases (in the fully destructable environment), they will become increasingly hostile and violent).
