Hm, hard to tell. To a certain degree, I also liked MC 2 more than MC1, but mostly because it has an editor and I could play in more than 1024 resolution. Besides that, it was ok, but it didn't get me as exited as once MC 1 did. It had better story (taking place in OP Bulldog), and the missions somehow even "looked" better, though it was only 640 resolution, and had a few nice animations. (I remember the cool breaking down building probs
) MC2 missions and engine always were quite ugly and lowres, sort of like mission areas in MW4. And that I bought the german version, sucked twice as much
The mechs and vehicles didn't blew me away either. It's now better because there are so many more models available right now.
Unfortunately I never could play the MC1 addon, it wasn't published in Germany. But one of my team mates wants to rebuild both MC1 campaigns, so with a little patient.......
