Halo?
I saw and played the game a few years back, when one of my cousins in Mexico got himself an Ecksbocks. I didn't know what all the fuss was about, as multiplayer co-op gaming existed since Quake 1, something I used to play as a 11-year old in an oldschool LAN arena in Warsaw, "Jaskinia Gier" which was located in a big media shop, Empik. Damn, those were the days of Q1 fragfests and Diablo co-ops. So no, I never got Halo's point. I guess the ecksbocks was the first to launch FPS multiplay on such a scale, as Halo itself was vastly inferior to other similar multigames.
I played FEAR for a bit, but it was boring. In the same way a few books can be terminally boring. Mickiewicz's Dziady and Stendhal's LE Rouge et le Noir are perfect examples. The crappy "sudden sound horror" coupled with the pseudo-creepy girl turned me down. Hell, Hl2 was a far more entertaining game, mostly due to the grav-gun, which let you kill enemies by shooting toilets and radiators at them, not to mention City 17 looks a lot like Warsaw, my second home-town. City. Whatever.
Anyway, when I'm going to buy a game, I usually do some research online on it. The only time I was disappointed was buying NWN2. The game could be almost bearable in English, but the version sold here had an extremely shitty, forced translation. To all you Poles reading this, it's the last fucking time I buy anything from CD Projekt. And to think I was going to work there. Ha!
So, summa summarum, I do some research from several sites before buying anything. Talking with friends that've played the game is also a good source of information. Hell, playing it at a friends' house is also insightful.
