Ralackk: Not sure about Dune 2 but in Warcraft you can get groups of 4 somehow I think if you hold control or shift and select them. I don't think I actually figured that out until I had beaten both the human and orc campaigns though.
Yep, you can, but you can't save the group for later use. And you still had to click on each individual of the up to four units, but after that you could move them as one. Worked okay for creating meat shields of knights to run ahead of the archers.
Most games that fit within the passable-but-not-stellar category of early 3D game technology have aged badly in my opinion. For example early FPS titles that weren't Doom or Quake. Redneck Rampage comes to mind - it's stull fun, sure, but mainly because of the redneck setting and different gameplay mechanics (farting, anyone?).
I'm also going to perform a cardinal sin and suggest that the M&M games haven't aged well at all, especially the ones in the 1-6 compilation found here. I tried playing M&M 3 and 4, just couldn't get into it at all. M&M 6 is slightly better but mainly due to the improved graphics. If you didn't play and love these games back in the day, they're very hard to enjoy now - especially when you can fire up Dragon Age instead.
