Fallout 2 feels like going on a wild roadtrip with your friends.....which is can be in-game too if you get the car
Correct, and it's not a bad thing. The main quest is an afterthought, the game even lampshades it by pointing out how ridiculous the idea of looking for a mcguffin that might not even exist is. Doesn't change that the locations you visit and the people you meet make Fallout 2 what it is. Even towards the end, in the very last leg of the game in San Francisco, you get to side between asian stereotypes or a scientologist parody and the game somehow made it work. The world still works even with the whacky stuff like the 50s gangsters, you know why a city exists and what it provides, where the food comes from, how one city and it's politics effect the other ect.
On the other hand, in Todd's games you move from one attraction to the other. How does that city work, what does it provide to it's people and the surrounding towns, hell what do they even eat? Don't think about it, just move on to the next whacky setpiece. Bethesda copied the funny but didn't have the chops to make the writing work, not even make sense. A lot of content in F3/F4 feels like a Wild Wasteland or a random encounter skit, but it's just something that we're supposed to take at face value.
I can't, for me the appeal of FO is the grim setting, I can live with humour on top, FO1 is my favourite in the series and it has plenty of goofy moments but the world just needs that bleak foundation for it to work for me. Just got to accept that 2 isn't for me I suppose, It shows how big a difference the tone of a game can make though, with them both being the same engine etc and one being in my top 10 and another being something I can't even bring myself to finish.
Fair enough, there is actually a pretty big divide between people who love Fallout 2 and those who say that Fallout 1 is the only true Fallout game. I actually prefer the darker, more cohesive setting of Fallout 1 as well, but F2/FNV are so good that I can stomach the setting becoming more flanderized and silly if the content justifies it. To not harp on Bethesda games again, Fallout Brotherhood of Steel follows a similar theme park ride and stupid, flanderized take on the world and it is an Interplay game, just like the older titles. Todd didn't ruin the setting, for as good as it was Fallout 2 started the trajectory and BOS finalized the journey. That said, Van Buren looked like it was going back to the roots of what made Fallout great and was going to be much more grim and dark, but alas, it never came out.
Anyways, like I said, I don't think anyone will hold that against you that you can't stand F2. This is a similar sentiment a lot of old time fans had during release of Fallout 3, they wouldn't touch it either for the same reasons and they were right. Just look where the franchise is today. I don't even know where the TV show falls into it, the dumbest shit from F2 looks downright good in comparison.
