No,
Mortal Coil wasn't any good*. Show-stopping bugs**, horrible voice-acting, and most of the neat things (like the waypointing system) were unnecessary or badly executed. Which is too bad because it might have been a decent game, but having interactive cutscenes just isn't enough.
And no, I hardly used waypointing and split screen because it wasn't an important part of gameplay, and my stupid team mates got themselves killed all the time once they were out on their own (think of the
Rogue Spear games - I managed to get through most missions of those by parking my men right at level start and doing it all by myself, using Maldini to sneak around enemies. That guy was inaudible even when running in full battle gear! And if I ever actually needed help, I used a guy for backup whose bio said that he was from my hometown
).
Cyberstorm, on the other hand... you're so right. The best mecha game ever, and probably the best game in the whole Earthsiege franchise. Why, oh why did they have to butcher the sequel so badly? Another of the few I couldn't finish. Difficulty was extremely high - I couldn't even get past the first mission. And they dropped the storytelling-by-hints-and-mission-files which made the first game so good.
