Are you certain that there are problems with games only? What about playing music?
Static noise can be hardware problem, try moving audio connection cables a bit.
It is really really hard to apply this model (or think of a similar new one) to all games. For example a (*gasp*) WW2 shooter, where you don't have a health meter or ammo LED display.

:D
As for screenshots, devs said that the toolset will create rooms without placeables, you add them yourself. So it is up to mod builder to give every room a unique look.
There were no new screenshots for a very long time. Shots at Gamebansee aren't new either, however they have creature renders that I haven't seen (can be new).
