If you've ever seen a comparrison of map sizes, some of the elder scrolls maps dwarf everyhing except Just Cause 2. They made an NPC walk from one side of their biggest game map to the other and it took the npc 3 days lol
There's plenty of gameplay in there froggy so you're getting your moneys worth if anything. Hundreds of hours of gameplay in there (tho not as much as RAGE which is said will have 3 discs for xbox and an 8GB install for PS3 :s)
I'm the sort who thinks, if the company deserve my money and I want the game they get it. Bethesda have done just that, people like trearch tho, they can go shove a 60.cal up their arses for all I care
I would get it on PC if I knew I would be getting a laptop good enough by then (my acer aspire 6935G doesn't have a good enough CPU or GFX so I can't play it on lappy) then I would buy it for PC. However I've not got a job yet and won't be driving till November so... yeah I'm not gunna have the cash for a good laptop anytime soon lol
