These arguments that you should not use a mac for gaming, or the uselessness of retina display, pscht. A laptop is multi-functional. That is, if a game can potentially run on it, then play it! Consider a laptop must also be used, by most people, for business or school, things in which mac excels.

I have a gaming PC, but not everyone is so lucky. Discrimination against macs is useless. Appreciate that they are popular and games can be played on them. Do not sip what they call hatorade.
