Games I've spent over 100 hours on.
Games are a varied lot. So many genres, mechanics, styles and their overall asking playtime make up for a shit load of variables. Some games can be downright awful and ones you wouldn't even want to make eye 2 case contact with. There are some can give you a quick adrenaline burst of around 8-12 hours, while some can stretch to a well paced 50-100. Those quick adrenaline burst, though, may bring you back for another run to experience that same excitement. Then there's the replay value most games will offer, and all in all, there are a lot of games out there that have the potential to take up months, years and even decades of your time.
Here I've decided to put up a list, in no particular order, of games for a multitude of reasons I have spent at least 100 hours enjoying myself with.
