Linux PC. Almost entirely on a desktop, though I've got a few games (Cataclysm: Dark Days Ahead, Caves of Qud) that I'll play on a laptop.

Very limited use of Android, if I'm away from a computer, for the mobility.

I've owned a few consoles, but the experience has consistently disappointed me.

• Loading times are worse (well, maybe this has improved, but historically was a pain)

• I can't as trivially flip over to a wiki in a web browser. I smack a button, I'm on another workspace on my PC.

• For some reason, a lot of "deep" games that one spends a lot of time learning, like strategy and milsims, don't have much of a presence on consoles. I like a lot of entrants in those genres.

• Games cost more than the PC. I mean, sure, the console vendor loses money on the hardware, has to make their money back on the games, but that especially makes consoles a bad buy if you're going to get a lot of games.

• The PC has more potential to be upgraded (though I'll concede that consoles have generally improved here).

• I'm not constrained by what the game developer wanted me to do; I can drop in with a memory editor and cheat in a game, can add mods to the game, have control over save state, etc.

The drawbacks of a PC are things that don't really bother me:

• You've got setup and configuration, which I'm gonna do anyway.

• You're more-likely to hit driver or hardware compatibility issues than on a console.

As for mobile...

I would be potentially willing to pay a lot more for mobile games than I do, but the entire commercial game infrastructure on Android is tied to getting a Google account, and I refuse to do that; I don't want Google logging and data-mining what I do. So I almost-exclusively use open-source software on Android. And most good mobile games have made it to the PC.

Honestly, I was kind of unexpectedly disappointed with Android gaming (and this is even based on what I see in the Google Play Store).

Okay, the touchscreen isn't a fantastic input medium for a lot of game genres, but I thought that stuff like multiple-choice choose-your-own-adventure games and gamebook-type games would see a huge renaissance, but some of the main games in that line have been...not that great; Choice of Games has a lot of titles, and some of the writing is good, but the gameplay mechanics are kinda disappointing.

Turn-based strategy games seemed like a good fit for the touchscreen, but as with the console, deep strategy games also haven't been hugely in evidence. As best I can tell, there's a strong focus on games that you can drop into for a few minutes while waiting in a line or something and then drop out of...which is fine, but really constrains the experience. I guess deckbuilders are okay, but the PC does fine there too.

A lot of Android games aren't super-considerate of the battery. Some games that I like on the PC, like real time sim games (Oxygen Not Included or Dwarf Fortress) require constant load and just wouldn't be a great match for a phone running on battery, even if they were present.

I'm not really into games that leverage location, which is one thing that a phone can do that other platforms can't. I could maybe believe that there could be games that could leverage multi-touch support to do things that PCs can't and really get a lot of good out of it, but I haven't seen that.

The screen has major limitations in that few Android devices have a large screen (so they can't expect to control a large portion of your visual arc) and on a touchscreen, your hands are going to be obscuring part of the screen, making things even more difficult for the developer.

Touchscreens have gotten better, but they just don't have reliable, rapid response to input the way that the mouse-and-keyboard (which a PC is guaranteed to have) or a gamepad (which a console is guaranteed to have) have.

Android phones can take external peripherals, but it's hard for a game to expect that they be present, especially since not everyone wants to haul a lot of hardware around with their phone. So you can get game controllers, earphones, a keyboard, or even an external projector, but it's hard for a game to expect that you have them available.
