Lab of the Dead waiting for the bars to fill
Spend hours watching the same few animations to farm "research points" so that you can spend more time waiting for a research bar to fill, while you keep rewatching animation farming more points to painfully research more stuff.
Wonderful idea, terrible execution.
But if beating a zombie with a stick so that you can research rubber duckies makes sense to you, and you are willing to spend half a day doing it, it's a great game.
