I hated how confudled the control scheme was and how non of the units (marines at least) responded to being attacked right up until the very last second... kinda made you wonder if they knew they even had guns
Also insti failing missions because your comm officer who kept you intouch with the reinforcement dropship decided to go walkeys and get himself killed got tedious after awhile.
Aliens were fun, dragging poor smucks off to be hosts for your glorious hive, and by glorious hive I mean 85% of the level
Worst Console port (for me at least) was Supreme Commander 1, basically take the PC version:
Turn the graphics to minimum settings
Limit the unit cap to less than half what the PC can handle
Blurr everything and I mean everything
Throw in a couple of unique units exclusive to the console (and make it so the UEF one is the only good one - infact make it gamebreaking)
Murder matchmaking with a pickax
Show PC gameplay footage at the start to mock your lowly Console experience
And the Xbox 360 still couldn't handle it, once you approached the max unit cap or if you had the audacity to load up a save made midgame then all the textures would turn shiny and silver, keep going and the audio would hang, and if you decided to launch more than three nukes during a large battle (with ground and air units) the whole game would freeze.
Handy tip, if you ever want to play an amazing RTS...
get the PC version.
