Completely interactive environments, yay or nay?
Remember that gap that you SHOULD have been able jump past? Or that slope you SHOULD have been able to traverse? Or that area which you never could get in but wondered what was there? Well, you can these days.
Should this be standard in games today or should the effort be put elsewhere? Personally when I find a game that allows me do some of what I said above, it added a great deal of interest with the game world for me and as a result I enjoyed the game a lot more.
