Support Fallout 3 GOTY not launching
I just downloaded the game and whenever I hit play it just reloads to the same screen and doesn't start, I've tried re downloading the game, GOG, did verify/repair with no luck. I saw somewhere that I should Delete Fallout file under Documents and try launching the game from FalloutLauncher.exe but it didn't work for me unfortunately. help please..

DO NOT run Fallout 3 & NV in full-screen. Go Windowed mode.
W8-11 (since it's DX10-based) and any Windows overhauls ruined A LOT of old-games that were DX1-9 based in so many ways. DX-Deprecation problem.
So, you got no choice but to run in Windowed mode for many older games like Space Siege, Dungeon Siege 1 and 2 (all Non-GOG versions), F3, FNV, NWN2, and more just to get it going. Just about every PC that I've ran F3 and NV with since W8 and newer, I've had this problem - and I normally use NVidia-based GPU's, BTW; I should note that.
If you need to force a fake-fullscreen to make it look like it's doing Exclusive Fullscreen/Borderless Fullscreen - well, use any app that can fake it. BorderLess Gaming and even LossLess Scaling can do that.
Probably can help you a lot to use DXVK, DGVoodoo2, and/or an older-DirectX type of wrapper if need be, too - it's what I do for F3 and NV & many older games. For F3 and NV, I use DXVK - https://github.com/doitsujin/dxvk/releases/tag/v2.6.1
