Really depends how i feel. For me, i see if there are walthrough videos, with no commentaries on youtube on the game, and i see if i like it. In this case it was Alien isolation.
First thing is that i looked to see if there was any videos related to the game that can explain it fully.

That really got me hooked. Mind you, i really liked alien before this, and the main thing about this game is the fact that it's the offical sequal to the first movie. I remember watching the movie when i was ten years old, around 1 in the morning on a shitty old television, so i already had a very positive memory of the series anyways.
I then found, well. A very high quality video of the entire game.

Recently i've played alien isolation, not a bad game, but you can tell it was rushed. You'll notice stuff if you look too hard. But it's still great. One funny glitch is that amanda will gasp in fear for no reason in certain areas and she'll do it over and over if you walk back in fourth
Really great story.
Anyways, that's what i do.
I mean, another thing is maybe i don't want to play the game, and i want to watch the game as if it was a movie.
