Yep. Gamers tell fibs just as much as everyone else does and you can feel free to admit it; we're all friends here.
If you don't have the one character in your gaming circle who claims to have completed a recent release and already sold it on for its entire RRP then what kind of gaming group are you!?
Bare faced lies on the part of the gamers - they should just admit that they can't afford to pay £60 for the latest Lego Marvel Avengers title and have done with it. If they refuse to tell the truth, you can always check their achievements and trophies to reveal the facts - Poirot style.
