I'll pre order anything gw2 related or gw1. Ill also pre order anything monster hunter related. These have been tried and true games to back blindly at least in my opinion.
I dont pre other new things anymore because most developers and publishers lack the history. For example Bethesda has always been a kitten company that delivers good games, the problem is that these games are rarely good on launch and rely heavily on user mods.
Gw2 or monster hunter in the other hand always deliver quality and thats why you see so little progression gameplay wise. They play it safe because they don't want their communities getting jausted around.
