I say keep the games, life is short. There will ALWAYS be expenses and obligations - the wolf at the door as it were. Kids going to school...or other (take care of elderly parent, etc). Stock market meltdowns. Divorces, etc...Selling those machines, buying back machines and moving them in...what a pain...
(Assuming you're playing them at least 5 hours a week): unless your job is very insecure, keep the games and live life. One day, hopefully down the road...something bad will get you. It's a mathematical certainty.
When your mortgage term comes up again, negotiate something better. For 100k you should be able to amortize over a longer period of time, get a decent interest rate. You shouldn't be paying that amount of interest on 100k IMO.
