Just tried it out with the various WAD files, and to try out the different weapons. Love the feel of the weapons and Caleb's voice lines.

A couple of issues that I've noticed. Firstly, when playing Heretic or Hexen there is no visible menu selector on the main menu (but in Doom, Freedoom and Hacx 2.0 you get the skull icon). Secondly, the HUD appears to be set for a 16:9 resolution, so on my current 16:10 screen the edges are cut off. Whilst the normal HUD only loses a small part of the decorative gargoyle at the left, the fullscreen HUD loses parts of the numbers at either edge, and further to this, the HUD doesn't change size when you change the HUD scaling values.
