Here are my impressions from the first time I played it yesterday.
1: easy to DL and load
2: not so easy to start. playing. It needs a... video readme that says "1289x1024(4:3) will work most of the time". I had to go digging through the forums to find this out and was about to give up on ever playing MCO.
3: load campaign screen is small enough I have trouble reading the text. Turns out that the load/save screen are the same way
4: mission breifing and just about every other scrren until the mission is launched is the same way. Very hard to rread a lot of the text.
5: I liked the map in MC2 better anbd I like the command interface in MC2 better. I can live with using the new ones though and in time will like them better.
I dl'd the Carver v campaign and am playing through it. it is a good update of the campaign. No problems installing it. If all the campaigns are the same way, I will try just about all of them eventually.
I like it better then the standard mC2 in spite of the things I dislike. MC2 IS easier to play since it does not have these problems.
MC2 my rating 8
MCO my rating 9
FYI I am running it on a stock Dell Dimension 2400, Celeron 2.4 GHZ, 2 gb memory, Win XP
