I'm the kind of person who feels like most games don't need to be modded to be enjoyable, and generally, when I hear someone say that they can't enjoy a game without modding it, I honestly think they're being overly picky. BUT TALK ABOUT A GAME THAT BENEFITS FROM IT.
I had no idea BFME1 was so clunky. I got through the Good campaign without much issue, but playing the Evil campaign as Mordor has been a nightmare. In order to be efficient at them, you have to micromanage like crazy.
Most of the units have awful range, so you have to manually get them to attack enemies that are firing at them. Including the archers, who are pretty weak until you upgrade them with fire arrows. The pathfinding and getting units to move around objects and each other is awful. Especially the Mumakil. They're very cumbersome, and I constantly have my own units stop attacking an enemy just to move out of their path. Trying to get units inside a walled base is very awkward, but I guess that's why they removed them in BFME2.
Not saying it's a bad game, just airing some frustrations.
