think a "witty" or "funny" response to this might come off a bit standoffish. If you're gonna go that route then you should actually follow up with what you really like to do. As per top comment currently, you could say "Bank heists mostly, but sometimes I just like to relax from all the excitement and play some video games or watch a movie." Or a much better approach to this is to actually start doing things that you don't think are going to be perceived as boring. Go out and hike or go fishing. If you don't like the outdoors, stay in and read a book or learn a new skill. Then when someone asks you could actually have a conversation with a wide range of people instead of just those that like video games ie. "I like to play Skyrim, which games do you like?" Will only be a good conversation for some people, wear as "I just read Kurt Vonnegut's Slaughterhouse five, have you read any good books lately?" targets a larger range of people. If you have a pretty wide range of things you like to do then you will have a much easier time being able to actually engage people in conversation and have something to talk about and bond over
