Perhaps a loose interpretation of “wasted”, but multiple different games have wasted a lot of time I would otherwise have spent doing more productive things. E.g. currently I have a side project that is actually really interesting to me but I have been spending my limited free time (with a toddler and an infant to keep up with) playing Deus Ex Mankind Divided. I may not end up spending an actual 100 hours in it, but I did a few years back with its predecessor Human Revolution.
