HCG 2002 is a very fun and enjoyable game. Nothing wrong with it.
Just to let you know, HCE has area ECM incorporated. This simply isn't available in HCG. If you've every played a game with ECM and compared it to one without ECM, you might fight it like night and day. Just try fighting a war without effective Prowlers or Raven jammers.
I hope that they'll release a demo some day so that you can see for yourself. The results will knock your socks off.
Until then, Happy Hunting in HCG 2002.
