All I can say is - just cancelled my GTA4 preorder on the PC... I desperately want something to play and immerse myself in and the only thing holding me back from Fallout 3 was the fact that I knew that without the modding tools, there was so much potential missing. Ive been following Betheseda games for years - Morrowind and Oblivion showed that the Betheseda modding community is one of the best by far in PC gaming (just take a look at the Oblivion and Morrowind mod forums to see the magic people do with the toolkits - the games become something else).
