I never actually played Fallout 4 (but i always kinda liked apocaliptic type of games). Im on PC..
Should i give it a try,since its like almost 10 years old game?
There's a lot to like. Bethesda make good worlds that are worth exploring. On PC you get access to all mods, and while to some that means changing the game drastically but to me it means enhancing the vanilla experience, UI, and general QoL.
It's the same engine (bar upgrades) as Skyrim, so if you've played that you know what to expect. If not, Bethesda's engine has its faults but it does persistence like no other engine out there.
FO4 as a game is less about roleplaying than the previous games because of the voiced protagonist. You don't really get to RP a character when you're stuck with the lines that have fixed delivery, but it's worth a playthrough and you do still get to make choices about your progression through the main story let alone everything else.
The main mods I go for on PC, and that I would recommend to a new user, would be a modern sort mod for the UI and turning the dialog from the poorly thought out 4 summarised options layout into a list of the actual lines said. The problem with mods right now is that any requiring the Script Extender (basically essential) will be broken until a new version of F4SE is released, so you would be a new user stuck choosing between waiting, going without, or getting into downgrade territory which isn't necessarily something I would recommend to someone who isn't familiar with the game, specifically with modding it.
If you're willing to wait a month or so, you will likely be able to get an updated version of F4SE, install Vortex as a mod manager, install
this collection for the UI improvements and
this for other basics, and after that pretty much get on with it.
