Well whatever you decide to get, you'll enjoy it I think. You can't go wrong with either console and both have great games on the horizon.

Where is the Dreamcast option?

What did he originally say?

Already got a dreamcast :)

In that case, probably the PS4. Though I don't understand why you want a new console when you already have a Dreamcast. 

I think the best games on the horizon are third party... Sunset Overdrive looks cool, but not neccessarily AAA must buy, and Quantam break / The Order look like they could be amazing, but SP only?  For me Watch_Dogs, Destiny, The Division, and Dying Light are the must buy games coming out soon. No exclusives are looking like must buys to me right now... However, h1z1 has really caught my eye!

There hasn't been a new Dreamcast game since 2007, and there is no more online support sadly

Xbox One if you want to play the best games and use multimedia. PS4 is you want to brag online about having a couple extra pixels that still isnt matched to a standard pc

True and fair point. I guess that means PS4 it is then. 

I would honestly wait until after this next E3 to make your decision. It's less than two months away now until the big press conferences. If you can't wait that long then I'd say to look up the games both consoles currently have as well as the games that have been officially announced and see what information there is on them. Which games get you more excited?

Most people will only tell you what they think is better based off their own opinions of what games are fun or just because they're fans of a particular brand "because reasons". In some cases they'll tell you that certain games are better than others even if we know next to nothing about them. Like the people who mention games like Shadow of the Beast and Sunset Overdrive. It's best to just ignore those viewpoints as they're pretty much just coming from a biased and selfish desire to see you buy the console they want you to buy. Not what's best for you based on your own preferences.

Watch videos of these games. Get information about them. If one console's exclusives make you more excited than the other then go with that one. If you can hold off, wait until this next E3 to see what's coming up. Going with what other people tell you is fun could very well just lead to you regretting your decision. Are you really willing to spend hundreds and hundreds of dollars on something that some obviously biased strangers told you was fun or would you rather make your own decision based on your own findings?
