keeping it actually related to OP's post
lived in sweden for 7 years as an immigrant from NA. I lived in gothenburg and stockholm (lidingö). You can see the entirety of gothenburg in about a day, there isn't really much to see. gothenburg is more of a laidback blue collar commie/leftist haven. stockholm is way more metropolitan and the hub for all industry in sweden, the vibe is much different. it definitely has more of a "posh" feel than gothenburg. also a lot of people from gbg "hate" stockholmers (butthurt). if you even have a competent level of game, itll be very easy to get laid. i am 170cm, pretty average looking and racked up about 60 notches during my time there. just be sure to approach, don't rely on dating apps and don't be a pussy.
liseberg is cool to check out if you like amusement parks though smaller than anything thats offered in NA
Haga is very cozy and one of the oldest parts of gothenburg
if you want to get laid there are 3 primary areas in gbg: kungsportsavenyn (often shortened to avenyn), vasa (vasastan/vasaplatsen) and around järntorget/andralåggatan
avenyn is the most posh and expensive area, vasa is kind of a middleground/hipster ish, andralång is commie/leftist central so be prepared
there is a nice shopping street on kungsgatan/around domkyrkan
other than this i can't comment much on gbg, it's quite a small "city". avoid any areas outside the city centre as its filled with niggers. as is the central tram/bus stop, brunnsparken. it's extremely dirty and packed with gypsies (there are roaming gangs of them everywhere in the city)
