I'm really quite strapped for time right now so again this is brief.
The latest Freedroid RPG release looks nice. The project seemed to have stalled earlier in the year but there's lots of contributors these days which is nice to see.
Want to make games but not a programmer? Maybe Mokoi Gaming is for you. The project is in it's infancy but it's already usable although the documentation is a little sparse. Still, it all seems well done so a bit of user feedback I'm sure will be warmly received.
Tennix now has SVG graphics. A very concise concept is turning into a nice little game to while away the occasional onset of boredom.
Also another simple game shaping up nicely is Qonk, with 5-minute galactic conquest gameplay.
No screenshots. No time to find any. :-(
