After playing Fallout 4, I just can't go back to the shitty shooting mechanics of the previous versions. I get the itch to play the game and then I remember how lame the shooting mechanics are and dont reinstall the game.

Which is why I use the VATS even though I like FPS/TPS games.

I just started to play Fallout 4 recently. And after going from 1, Tactics, 2, New Vegas, 3. So, finally I can say "Well... of course"

Fallout 4 is a FPS while Fallout 3 and New Vegas was more a "real time" approach to the original combats in turn from the first games. The percentage of shooting is there, and your skill have an impact on it. And... VATS, you need VATS in early levels, and even in high levels. So, yeah. F3 and New Vega falls poorly if you are looking solely FPS.

P.d. Strangely, I found more logical that my dweller or courier slowly became proficient with weapons that a law graduated be a redneck .

My first Fallout game was 3, followed by New Vegas. I bought 4 at release and have always hated it. Went back to 1, 2 and tactics and muddled through them. And we don't talk about 76.

New Vegas is one of my all time favorite video games.

4 plays too much like an FPS for me. I could enjoy it if I tried to picture it not as a fallout game, but they kinda try to keep that in your face once in awhile.

I enjoyed 4 with a realism mod that added modern guns and all sorts of calibers and made pretty much everything a 3 shot kill. (I only play HC on call of duty)

You can get a pretty satisfactory gunplay (definitely better than F4's) with the proper mods
