My Dad loves playing my brother's PSP, often I'll catch him picking up Brother's in Arms and setting himself away. But before that he played loads of games on the PS1 and PS2, he was the one who introduced me to Crash Bandicoot, Metal Gear Solid and GTA, among others. Before that still we had a Sega which me and my sister would watch him playing endlessly, we hated when Sonic died.
My Dad is one of the reasons I got into gaming.
