I have the same "problem" here really, loads of ideas.. And at the moment not really skilled to do it all ;-) But I haven't seen much of these kinds of game since, ehmm.. Jagged Alliance 2 was released.. hmm.. I gotta play that one soon ;-) I can't get X-Com UFO to run on this computer.. yet..

The problem with X-Com 2 is that some scenarios were abit too big, and took ages to complete like the boat-capture.. And then if you ran into it at the start and having to fight against thost Lobsters you'd be stuck since your firepower at that point sucked. And I'm not going to say anything about no. 3.. *sigh*

But I guess there is a million ideas to get this "idea" into a pretty nice game, problem is however not to overdo it ;-)
