Dune 2000, being forced to build concrete under your buildings.
I've only ever played Dune 2. What was the issue?
You have to build concrete on the sand and then put your buildings on top of it. You don't have
to, but if you just build straight onto the sand, your buildings take damage slowly, so it's a lot less cost effective having to keep repairing them than putting them on the concrete.
I imagine he found the process annoying and thought it brought nothing to the game. Me, it took a bit of getting used to, but it didn't annoy me after that and soon became second nature.
