My first iMac (27", GTX680MX) will hopefully be dispatched shortly, to replace a prehistoric windows PC (2004). Being both unfamiliar with apple and 5+years out of date with games.....I could do with some help with the following 'basic' newbie questions : (i) Which games run fluently in OSX on new iMacs (which ones don't) ? (ii) Where are the best places for a UK resident to download OSX games from ? (Am I restricted to EU sites ?) If (i) is too open a question, I'm particularly interested in strategy and fantasy RPG games - so Civ IV (complete edition) and Starcraft 2 might be a starting point. Any recommendations for a really good OSX RPG?
