I will say this even if Obsidian came outboard to help make a remaster I don´t even think they would know how becuse obsidan has proven that 1.
1.They can´t make a good game like new vegas again it was a 1 hit wonder.
2. They are so busy focusing on modern games for no existing audience "so called modern audience".
having played Avowed and the outer worlds I even start to question if they rely did make new Vegas honestly im sure they got the credit they don´t deserve.
Or maybe people are blowing new vegas up the ass way way to much. Because all their game sense has been crap or mediocre at best not even close to new vegas good.
I will say Fallout 3 and New vegas could stand to get a remaster or at least an engine upgrade to the newer version of the creation engine. Because I will say this new vegas and 3 modding is the worst.
Fallout 4 I can run 200+ mods not a single issue runs smoth and never crash. When ever I try modding 3 or new vegas 15+ mod and you start to crash or get other issues.
When I recently wanted to replay vegas I had to follow this dang
FNV Performance Guide to get the game running smooth with mods and it´s SALVER pages long.
And the worst part the amount of time it take to follow that guide and get all the mods to work properly with out creches or in-game glitches I could have already spent 20 hours downloading mods and playing fallout 4.
The reason why I hate new vegas so much modding sucks ass. I hate the setting of 50 shades of sand and the gunplay is bit on the wonky side and honestly the only thing the game has going for it is the story.
But to me a game need more than a good story to be enjoyable. Just the same as a game needs more than graphics to be good I don´t care if the game looks hyper realistic if game play and story is trash.
So my honest opinion if they can´t remaster new vegas and fallout 3 is to focus on fallout 5 and maybe if they want make new big DLC for fallout 4 that would be nice becuse I gladly play more fallout 4 that can be modded and runs better.
In and honety fallout 1-2 + 4 are the ones I rather play over 3 and new vegas. Becuse at least they don´t frutrate the hell out of me.
