I agree with much of what you say, although as I only came to gaming in 2001 I can't get into the older RPG's such as buldar's gate and Morrowmind because the graphics are so primitive. I could probably enjoy them more as pure text games than trying to play them as they are. I agree that most RPG's cater for a younger audience & that bad voice acting is worse than no voice acting at all, as others have said dragon age & the witcher series work better for us older ones, the big problem I've had with, certainly witcher 2 is the QTM difficulty spike early on, I haven't tried W3 yet, been saving it, but to this day I still haven't been able to kill that damn krackenlike pond monster early on, my reactions are just too slow, hugely annoying...
I totally agree about the DLC I think this is just pure profiteering by the games companies, and I won't buy it until the price comes right down, which means that, generally I won't buy a game until it's been out for a year or more to avoid the frustration of waiting until the DLC price is right or feeling totally ripped off if I don't wait...
