There are way too many problems for Civ5. It makes the game seem unprofessional and makes it seem like it is still in beta section. They should have been able to see all of these problems when they were playing through the game before launch. Dear game designers, you have failed you're fan base.
I don't think Civ5 had too many issues at startup compared to other contemporary games. It worked fine on my system from the first day (due to being in Europe I had to play the demo for the first 3 days, and it was quite enjoyable). Elemental: War of Magic is an example of a really disastrous launch. But maybe this thread is not the best place to discuss such things...
