Sony - When the ps3 came out it had the OtherOS feature that allowed users to install Linux. This was the main reason I bought a PS3 instead of other systems. From the beginning, it turned out that Sony crippled the OtherOS by restricting resources that were available to it.
After a few years, they removed the OtherOS feature, because someone hacked it, which could possibly lead to pirating ps3 games.
They sold me a PS3 based on a specific feature and then disabled that feature. I will never knowingly buy a Sony product again.
This is a pretty good list that balances how fun the game is with complexity and popularity. I've played all the games except Star Wars and War of the Ring, and I liked them all (except maybe Gaia Project, because I like Terra Mystica more).
Of course there are a lot of war games that are more complicated, but I can't think of any war game that's more complicated, more popular, and more fun than the games on the list.
I don't know the author of the article, so, for all I know, they might have just searched for the top complicated games on BGG, but the result is a pretty good list.
