I've never been one to complain, and wonder exactly why people seem to think the game is buggy. I can't see a problem with the UI and there are the occasional bugs, like the game will crash if you play for too long, but I've never really let it bother me. I only get angry when I have a lot to do for a turn, and just as I'm about to end my turn after doing it all the game crashes
Recently I started looking for some new games after my long term ones wound up and I was astonished that when I checked PBW for SE5 games there really weren't as many as I would expect. It really started to worry me that games could become nonexistant.
