Well, I install the game, plug in a controller if applicable, launch the game and...play. 
Seriously, though, I use a laptop for space issues. And because I like to be able to play with my games even when I'm not at home. 
Smarty pants ! LOL
That's not what I mean . My roomate has a Laptop . But..I mean , it just so tiny . You should see her mouse..its so small lol and everything look flat .
And how do you play ??? LOL It just so different !!
I have been on Tower PC...since the PS1...and I aint gonna change since I'm so used to my Giant Tower purring next to me on my Desk .
I always though laptop weren't strong enough to play games...and Tower were best for games . Thats why when I hear 'I play on laptop' ...I'm like ...'Really ? You can ?' .
