Supreme Commander.. its just too big. You make a massive army to attack and it just gets slaughtered by base defenses.. its all about the experimental units which just smash everything in sight.

That just proves the fact that SupCom is a real RTS. Maybe you should try it again, but try with more tactical perspective now? There is no sense marching your army against endless lines of point defense turrets. Try to find a weak spot in your opponents defenses, or use artillery to break his PD lines. If he hasn't got AA, then attack with gunships. If he has AA, then just shoot the PD turrets and AA turrets. I should also note that it isn't all about experimentals. Again, don't try to destroy Galactic Colossus with a land army. Hit it with air units like Strategic Bombers since it is its weak spot. It has no AA. You just need to figure out the given units weakness and exploit them. ;)
