Before then it really was mainly war games (warhammer et al), RPGs, and card games (Magic TG from about 1993 onwards).
There are some absolutely fantastic games out there, but just don't buy from the top X games. Know the size of your play group and buy to suit them.
For example Agricola is a great game, but works best with 3-4 players. My group has 5 players so it's "ok" https://boardgamegeek.com/boardgame/31260/agricola
Recent games that have surprised us. If you like poker, Sheriff of Nottingham and 5 players is exceptionally good fun in a group prepared to be able to put on silly voices and get into character. https://boardgamegeek.com/boardgame/157969/sheriff-nottingha...
Also Camel Up is great for parties (up to 10 people with the expansion) and kids love it as well but is a lot of fun in groups of 5 https://boardgamegeek.com/boardgame/153938/camel
Group dynamic is important in buying the 'right' game but you cannot go wrong with Settlers of Catan if you can get 4 players. https://boardgamegeek.com/boardgame/13/catan
If you have a local game shop, or even better, a local games cafe, you can usually get a chance to try out a game. Just remember to buy from them. They are your gateway to a whole new dynamic computer games has pretty much tried to destroy.
Board games are so so so good these days, just avoid Monopoly. ;)
