It is a minor annoyance. More than offset by conveniences like BC and exclusives. At the root of this issue is price. Yes, a game of 10-12 GB can be put on a BR disc but will you pay $100?
Prices have crept up here in the frozen north. DA and ME2 were $69.99 cdn. $80 once we pay the guvmint. That is pushing the limit. The exchange rate should add $6 on a hundred not $10 on $60. Taxes are not BW's fault but that is more than I want to pay and more than Americans would ever accept.
Sound compression and video resolution, especially in cut-scenes seem to be bigger issues than play time. Bethesda has managed to put gigantic hd games on one disc. What's the diff.?
The industry has long adjusted content to a price point set decades in the past. That may be changing soon. I would rather pay $50 for a game that fits on 1 DVD9.
