I voted 'bad'. If there were more poll option, it'd be more in the area of 75% bad, 25% good.
Look...let's be honest here: console wars are a pissing contest. Back in the day you could argue that there was real innovation in play, but that's certainly not what drives sales nowadays (okay, nintendo still does its own thing. They're the exception). Consoles are basically computers you connect to your television. Heck...even the inverse is true, with many non-console PC games catering to the classic xbox360 controller. And that's a good thing: consoles as a whole should be a platform for a gaming audience. The whole exclusives thing is stupid, and if I had my way, manufacturers just produced their games on true multiplatform to begin with (meaning: if you bought FutureGame, you could download and play it on your Xbone, PS4, nintendo, PC and - give it a few years - your mobile device). We don't expect art lovers to classify whether they should like paintings on white canvas over paintings on grey canvas...right? We don't expect roads to be "mostly functional for all cars, but some roads are exclusive to BMW's".
Developers just want their games played. This whole mess of different consoles burdens them more than that it gains them (the exception is for anticipated games that gain benefits for exclusivity, but that act is more a symptom of what's wrong rather than an actual benefit).
The 25% good is basically what others have already mentioned. I can't deny that this whole "my console versus your console" gets people caught into gaming more than they otherwise would. It's like rooting for a sports team: it's not that you want the other teams to fail per se, but you certainly want YOUR team to be the best. Consoles give gamers a sense of identity. While I find it often a rather restrictive identity (see also: the hatred against mobile games), it is better than no identity at all.
