So you see kids, making a game like New Vegas it's like throwing pearls at the swines.
Could New Vegas have been better without the limitations Bethesda imposed? You bet.
But those two sheep not liked the game for all the wrong reasons.
One of the main reasons and probably the deciding factor why I didn't have fun with it is the shitty FPS gameplay and how VATS feels like an afterthought that is an instant win button for some builds and completely worthless for others.
I always value gameplay much much higher than anything else so this game simply is shit in my book.
Just like Morrowind: char building and tinkering with the systems is fun at start, but they didn't even try to balance it, also cardboard wiki NPCs and the kinda great lore not translating into interesting stories for the player to experience in most cases with the exception of the dwemer, hiking and just exploring/experience collecting is no option either, you don't need the experience and there are no challenges left much too early
and Oblivion: floaty combat, boring world not worth exploring, levelscaling, quests were better than in other Bethesda games though but who cares about that stuff
I like Daggerfall, Skyrim and now FO4 more than those games. Daggerfall doesn't have such a fast difficulty drop as Morrowind when you build up your char and it has even better RPG systems, also for some reason I like huge-ass dungeons that are difficult to navigate. And Skyrim is just popamole fun as long as you mod it. Dungeons are better than both Morrowind and Oblivion (albeit linear as hell except for Blackreach and a few other exemptions) and exploration is fun if you just hike for a while and ignore the story.
Fallout 4 is a nice shooter with interesting enemies (which are way too dumb though, but the behavior patterns mitigate that) and a postapoc world with some nice POIs and a tolerable level of derp.
Gameplay is everything, save the princess, find the McGuffin and destroy the big bad and similar uninspired stuff make for excellent computer games more often than not.
Good stories and lore (never read a single book in Daggerfall and didn't miss it) and shit are more like cherries on top, nice to have but not the real point of games.
So long story short: I wouldn't have minded the boring start and the abomination of a faction that's the Legion if the game had good gameplay. It doesn't have that though and the systems are not that much better than in FO3 anyway when it comes to the thing that CRPGs simply have to get right to be any good, combat.
Blame the engine, blame real time combat with guns and free movement, I don't care, it just underwhelms.
Maybe if the story would start with a bang and get even better from there on then I might have played it just for that, but the way it is: unsalvageable even with mods
