Why is that even a question? As long as people purchase enough consoles and console games to justify their manufacture, consoles are relevant.

So far both PC and consoles/handhelds are becoming more and more irrelevant (well, at least to me). Both are riddled with problems (whether it be DRM or just hardware/software design) and only have a hand full of exclusives or special projects (second/third party as well as indies) that really interest me. The Wii U and Vita are likely going to me my last purchases. Although the PS4 with Bloodborne as well as a few other stuff (and god forbid The Last Guardian) might be an exception, there's not enough for me to justify a purchase.

Disagree why? Just search for those titles sales by plataform and you'll get the idea, AAA titles sell better on consoles, why do you think they make half baked ports to pc? Why do you think they bother with drm?

As for indie games, i'm not saying that they're no selling well on consoles, i'm saying that they're easier to make on the pc, easier to release it on pc and there's more of them available on the pc than on consoles.
Indie market wouldn't suffer that much from the disappearing of consoles, AAA on the other hand would.

Well I saw some articles online talking about how PC gaming incomes surpasses consoles incomes but you are right, those AAA titles definitely sell better on consoles.

Even though I am 90% a PC gamer (and 9% Android tablet gamer, and 1% PS2 and Playstation gamer), it is obvious consoles are where the most money is made, at least with AAA titles.

I'm just glad that PC is still a viable gaming machine, but I must admit I was a bit surprised that even though Minecraft was a PC-first game and sold buttloads on PC, and PC is probably the best platform for it at the moment (considering the modding community etc.)... still Mojang announced recently that console sales of Minecraft have already surpassed the PC version sales (I took that to mean that they have now sold more copies of Minecraft to consoles, than to PC all these years).

Frankly, I was surprised. I was expecting it to be more like Starcraft or Half-Life, ie. even if there were console versions, I presume they sold quite little compared to the PC version (or so I believe, at least).

To me PC vs consoles is a bit like GOG vs Steam, I guess. X-Wing and Tie Fighter may sell quite briskly on GOG... but if and when Disney releases them on Steam, I presume they will sell 100x more there. Yet, that doesn't mean that GOG isn't making profit, even if there is a huge behemoth beside it where the masses buy all their games.

That's because you (or better, those articles) are talking about the income of F2P games like League of Legends, World of Tanks or Dota 2 and that mmorpg monster that refuses to die, World of Warcraft, they're not from retail/digital sales of AAA games.

To give you an idea, LoL this year generated $946 million dollars...

I'm a 50% PC gamer and 50% console gamer (PS2, PS3, XBox, Xbox360).
The only games I play on PC are older PC games and indie games, not modern triple-a games.

I prefer to play triple-a games on my console and not on my PC, for a number of reasons:
1) the PC port is usually much less stable than the console version, stability is more important to me than graphics
2) I can play virtually every console game offline, no "permission" from Uplay, Steam or Origin needed
3) I can spend more money on games as opposed to the expensive upgrades needed to play triple-a PC games

You can look at it from another perspective as well: the only games that are unique to PC these days are older PC games, complex strategy games and MMOs. Increasingly more Indie games are released on console, and more MMO-type games like Destiny and The Crew appear to be on their way as well. In this respect consoles are just as relevant as the PC.

The advantage of the PC is that it offers niches that simply wouldn't sell well on console, like a Tex Murphy game, or games that would be difficult to play with a controller, like a 4X strategy game.

In general, as long as consoles offer easier and more convenient access to games than the PC does they will always be relevant.

1) You're right. Except when we're talking about stability in framerate. :P
2) Mostly true.
3) Upgrades do not need to be frequent. PC games tend to have more sales and deeper discounts. (from what I've seen) So it balances out in a way.
4) Yes.

1) That would probably be due to a bad port. Ubisoft for example is well known for giving half assed PC ports.
2) Hmmm.. Much more a DRM selection. Much like cigarettes, cigars, alcohol, or chocolate cake, it's choose-your-poison.
3) Really depends on the games and how you approach it. If you have to get the exclusives from all three consoles, you're spending something like $1,200, and in a year or two when they bring out the Xbox-Bling, Playstation 5, and Wii-Triforce (i'm guessing) you'll probably have to drop another $400+ per console. Instead if you took the $400 per console and added it to your rig, you'd quickly be able to play even the highest end games relatively easily, plus you could still use it to do word processing and spread sheets.

Oh let's not forget, games on console are consistently $10 more expensive per game, and you won't see huge savings and frequent deals at Walmart or GameStop taking games up to 80% off...
