I liked TES before, but as the game progresses further and further it becomes more apparent to me how clunky its melee combat (or even in general) is. I've logged tons of time into Oblivion and Skyrim but at its core, I gotta say the melee is pretty poor. Mid to late game everything devolves into a battle between tanked up damage sponges. It becomes much less exciting at that point.
Fallout's reboot as an FPS however, I feel has turned out pretty well. Weapons feel different enough to warrant using. Damage dealt by me and my enemies always feels significant. Leveling doesn't just increase my stat numbers; the perks are different enough to allow very different approaches to gameplay. Any problems I had with it tended to be on the technical side. Crashes, load-screen loops, corrupt data, irregular enemy movement, etc. Those however, are all things that can be fixed.
It just seems to me like Fallout's flaws are less fundamental than TES's. I think it's a bit easier to improve the technical side, than to reimagine combat from the ground up. For that reason I don't see any more TES games going anywhere terribly interesting. I'm much more curious to see what they'd do with a Fallout sequel.
