i've bought nearly all my systems about a year or more after the release date, like the ps3 i waited 4 years cause i didn't like many of the launch games.
the only games i've gotten brand new on launch day were dragon age awakening and kh2 and my dad is actually the one who got me kh2 at 6 am in the morning so really the only game i got on launch day was dao:a.
alot of games i got used and for alot of them i got them cause i either wanted to purchase something, i was bored, or i wanted something to blow time on.
examples would be, i bought rogue galaxy [still have yet to play it] cause i wanted to buy something, i bought ff13 cause i was bored [turned out to be a decent game] and xenosaga 1 and 2 cause it said on the back 80 hours of gameplay meaning i was very bored on that trip, it turned out to be my top fav story based rpg series.
most of my games were gotten on the bases of those three conditions. some games like action games i will research it, but most rpgs are "i'll buy it regardless of the rating" this is because i fail at action games getting sonic unleashed with no research is what converted me, the whole game is timing, timing, timing. i hate those games, which is why regardless of my love for kingdom hearts i'm not getting birth by sleep, i've seen what is in store in that game and it is something i cannot play, all those timed reaction buttons are bull. the only thing that would make me get it is it is xehanort's past after all.
