Peoples taste in game genre can sometimes change and is usually early when a gamer is new and has yet to find the right genre for them.

So my question is: Was the game genre that you used to love still the same one that dominates what types of games you buy today or has it changed to something different?

For me I used to mainly play Platformers; being more exposed to other genres, RPGs/JRPGs are now what I tend to play most

I used to be all about adventure games.

While I still love that genre, platformers have become my #1 now.

Rpg/Jrpg's have always been my favorite genre. That will never change. Use to only play nothing but rpg's and very few fighting games when I was younger.

Though with the rise in popularity in FPS games when the ps3/360 came out I definitely became more open to trying shooters and other genres. Which is good is beacuse BioShock became one of my favorite series.

As an N64 owner it was all about the 3D Platformer, since then though I main JRPGs and other Japanese games. Also the complete lack of awesome 3D Platformers sucks =(

Not drastically, but I've grown a taste for puzzle/FPS/WRPG/fighting games.

My favorites will always be platformers, racers, simulators (tycoon games) and adventure games.

Kind of, yes. I used to be all about RPGs, though the only reason that changed was because they stopped making them for awhile. Aside from that, I was mostly into third-person action games, which I've mostly lost my desire to play. Button mashers don't really do it for me anymore. The same with fighting games--I used to play games like Mortal Kombat, Soul Calibur, and Street Fighter every single day but now I can't get into them much.

Fallout 3 was a pivotal game for me. I hated FPS games in previous generations because they were all corridor shooters. Once I got a taste of FPS games where you could play at your own pace, I was hooked. FPS game-play really benefited from the upgrade in graphical ability. Next to RPGs, single-player focused FPS is now my favorite genre.

At first, RTS games, "tycoon" games and racing games were my favorite genres, then I started to like platformers thanks to Super Mario 64 (I had played the older Super Mario Bros. games before but I didn't like them that much, I wasn't really too much into video games, though), then I played Ocarina of Time and I started to love the action/adventure games with puzzle solving, then I played some JRPGs like Chrono Trigger, Kingdom Hearts and Paper Mario and fell in love with them, nowadays JRPGs are my favorite genre but that doesn't mean I don't like the other genres I mentioned before.

I was all about point and click adventure games and real time strategy games like Starcraft and Warcraft. A PC gamer to the core. Now I game mostly on consoles and I love RPGs and open world games. I will play anything with a good single player campaign. Most hyped for game right now is Thief. I remember the first one very fondly. Ah, looking glass.

Initially, platformers and beat-em-ups. Then, action and shooters. These days, RPG's and puzzle-platformers.

Tomorrow, who knows?

Didn't change. I always loved RPGs, especially JRPGs. I also always loved open world games and arcade racers. If anything, over the years my taste got refined and more clear so that I tried fewer and fewer games from other genres.
That isn't bad though because I have pretty much a guarantee that I will love a game(or at least be absorbed into it for a substantial amount of time) if it falls in my favorite genres.
