Which one of these have you tried? At what point should it just be a computer game?
Personally, most complex game I tried is Ark Nova which did not even make it on this list.
Even some simpler games can have a lot of dependencies that make playing tedious like Hogwarts Battle
To be fair I was expecting a lot worse from a videogame website. It may not be the absolute top 10 but it’s a plausible list of some of the most complex games that the average boardgame player is likely to encounter.
For comparison, BGG search for gameplay weight over 4 and at least 100 votes
(which needs to be taken with a grain of salt too but it’s what we’ve got)
