Dammit JarlFrank, you're going to make me buy Fallout 4... it is still expensive though, not going to risk it.
I got the complete collection during a sale for about 15 eurobucks or so.
While the quest design is mostly meh and the writing is pretty dumb, at least it's not as bad as Fallout 3 (there are people on the internet who claim Fallout 4 raped the lore, but these very same people think Fallout 3 was good... I don't know what they're smoking, Fallout 4 is much closer to Fallout in atmosphere than Fallout 3 was). The basebuilding element can be completely ignored. I turned the gas station you find at the start into my home base, built some crafting stations there to improve my armor with, and that's that.
If you play it like your typical Elder Scrolls game, that is exploring the world and doing sidequests you stumble upon rather than following the main quest, it's pretty enjoyable. You do need some mods to fix the HP bloat at higher levels, but once you got those, you're set. The landscape is pretty varied and there are several really well-designed locations that make use of verticality and multiple angles of approach. Shootouts in old factories populated by raider gangs are fun: you climb up the various ramps and ladders while being shot at from above and below, seeking cover and trying to take out your enemies one by one.
It's not a good Fallout game (but it's a better Fallout game than Fallout 3), it's not a good RPG, but it's a fun explorefag experience.
