because Steam is once again crashing my computer. Last November, after trying to fix the problem for about a week, I reinstalled Windows. Not interested in going through that again so soon. Funny, the release of the newest client update coincides with Steam crashing my computer. All attempts to fix it failed.
So, fresh install of Oblivion (hurray for discs only games!) full of mods. Rather play Skyrim, but Oblivion with quest mods I haven't completed yet should last a while.
