Winter and being in doors for months at a time. And the graphics look amazing, saw a friends child playing a shooting game and thought I have to give it a try..
Plus bored with TV shows.
Having grown up without games like today, I'd say there is a lot of violence compared to 20 or 30 years ago.. But I do enjoy it.
Had to remind myself when driving that I can't just run over slow walker in a parking lot.. LOL No kidding..
But will ever know for sure..
Currently there are place in our solar system they say are a lot like ours, where there could be gravity and conditions that resemble ours.
