My biggest problem with MC1(Gold): Weird, weird fog of war system. You're telling me that as long as I've visited a location once, I get to see everything that goes on there, forever? Also, you can't reveal any farther than short-medium range(unless you get up on a hill). There are sensors on every 'Mech, but you still can't designate targets until you can actually see them.
The more BT-like ammo limits on the (non-LBX)autocannons were also kind of annoying, especially without much limitation on energy weapons. Ten turns of AC20 fire will probably last most of a standard lance v. lance engagement in CBT, but goes a little too fast in most MC or MW games.
"" MC2: AI. Seemingly, unless units are guarding or following waypoints, they will forever attack the first target they see until it dies, to the exclusion of everything else. Sending a fast scout 'Mech to pop into enemy LOS, then drag them right through your main forces' guns is a virtually painless way to cheese 90% of the campaign.
Even if you don't try to exploit they system, it's pretty ridiculous that the AI won't pay any attention to the pair of Hunchbacks that just jumped in behind its units and is now ripping them apart. MC1 AI units did very much respond to newcomers closing and firing on them.
The loss of ability to purchase/deploy major combat vehicles was kind of sad, too(Alacorns!
). Fixed artillery and Scout 'Copters with MGs don't count.
At any rate, any kind of development on MC2 is definitely welcome news.
