Gamebryo Lightspeed engine:
I have seen the Gamebryo Lightspeed engine and I have to say that considering its origins it actually looks good. The ability to deform landscape mesh sounds nice but I doubt it will be up to the geomod engine which was brilliant fun to blast about with. Lighting has lot of promises given and with its past history of crappiness and my constant frustration over glare and bright spots on objects I hope they offer more control.
If I can get round to trying the bloody thing out, it should provide a suitable environment to create a world of my own. The new game tes5 is supposed to use the Gamebryo Lightspeed engine so it holds promise of an existing world and items I can abuse to my own means.
