I can relate to this. I own more games now than I ever had in my youth and have a limited amount of time to game. I find it hard to get myself to play a majority of my games unless they are actually good games; this was not true when I was young, when I would replay crappy NES games ad nauseum just because that was what I had.

I find myself going in cycles. Sometimes I feel sick of FPS games, fighting games, racing games, platformers, etc...

With that said, it seems that I have reverted back to the genres I used to play growing up: FPS, platformers, and point and click games.

RPG and RTS games are still genres that I am trying to break into though.

That's why I pretty much require RPGs to have a good quest log so that I know my current objective even if I come back to the game after a long hiatus. That's the problem I had with e.g. Baldur's Gate with its poor journal system, I had hard time tracking what exactly I was doing, hence I ended up restarting it from scratch a couple of times.

Same goes with many adventure games, I have no idea what to do and where to go in some Monkey Island game if there has been a break from it.

RTS games are quite good for me in that sense, I can easily continue one even if I haven't played it for a long time. FPS too, I guess.

Atari == Riverraid, Combat, Pong, Frogger, Jungle Hunt
Sega == pretty much Sonic, Aladdin and thouse types, and DUNE
PC == Dos based FPS, some Sierra games (LSL)
PS1 == side scrollers and some racing
PS2 == Racing and 3rd person style (GOW/DMC) Prince of Persia's
GameCube == 3rd person adventure, FPS, Racing
PC upgrade == FPS, ARPG and Isometric and pure FPS, Open World
PS3 == Racing and 3rd person (GOD/DMC)
PC massive upgrade == FPS, ARPG, Isometric, Open World

Currently == Space Sims, Open World, FPS, Some Adventure.

This spanned 25 years

Yes. Younger - more RTS and FPS games. Older - more strategy and RPGs. I probably should switch those because playing strategy and RPGs take a great deal more time and concentration... things I increasingly have less of.

Not a lot of changes, but surely I do not appreciate games for the same reasons and in the same way. The only major change is that I'm loving lengthy RPGs more than I used to.

As quite possibly the youngest member on this forum, I feel some strange urge to comment here.
You could consider my parents to be the people whose gaming has gone the most unchanged because their tastes carried over to me. My addiction to adventure games and love of puzzles (although I'm a bit more diverse than that) started from watching/playing games such as Myst 3 and Police Quest with them as a kid (I think we still even have the 6th King's Quest box somewhere - the one with the minotaur on it)
If it seems I love the Adventure Company and Dreamcatcher Interactive a lot, it's because we have boxes and boxes of CDs of those games.

Kinda. I used to stop reading any review the moment I discovered that the game in question was a real-time/turn-based hybrid, like Fallout for example. And now Fallout 2 is my overall favorite rpg.

No, not really. Demographics have changed and what used to be in vogue are no longer hip with the younglings. But I still game for fun the same way I did back when it took a C64 game 15 minutes to load Yosagi Yojimbo on tape or whatever. I never really cared that much for challenge but only did stuff for fun - like gunning down civilians in Commando Libya at the end of each level (for reason that will forever escape me).

I like games like Dark Souls, Fallout 4, Just Cause 2, Skyrim and many others for the same reason that I loved old C64 games like Beer Man, Skate or Die, Ikari Warriors, Test Drive and Summer Games....

Because they are FUN!

Man, all these RPG players and no adventure games? No wonder everybody hates my puzzles, I'm beginning to understand it now.

When I was younger I completed Elite and Heavy on the Magic on the ZX Spectrum, and had severe problems winning in Civilization.
Now I can't into space games, and can't understand how I could even survive the first few minutes in Heavy on the Magic. OTOH now I play most turn based Strategy games on Impossible, and curse the weak AI.

I still enjoy CRPGs and FPS's as much as before. I no longer have the skill for some real time games, but fortunately it doesn't apply to FPS's or Dungon Master clones.
The last Adventure game I tried to play I was told I could go in various directions, including East. I typed "Go East" and was told that I fell down a cliff and died.
Life's too short for such shit.

Yes, more casual and puzzle games that can be played in short bursts with long intervals in between instead of proper CRPGs due to a simple lack of time. :/

The less time I have to play, the more genres I drop. I dropped strategy games, even though I enjoyed them, and I dropped MMORPG's. These days I mostly play adventure games, and occasionally try an RPG, but only those that run on my tablet.

I play more Action-oriented games now than I used to when I was younger, not sure exactly why .

In my case my likes didn´t change, they just expanded. From time to time they grow heavier towards one genre or the other but I never cease to like them. I switch to one or another as they start to grow heavier on me, but I always go back and forth between them.
