OPEN WORLD
The first trend that became clear in this year's E3 is the open world trend. It is probably due to the extra power provided by the new generation, it is quite an obvious path to follow, I mean you have extra hardware power so the first thing that comes to mind is "lets make it bigger" and the result is immediately and open world game. I am not sure if this trend will bring us more immersive worlds or if it is just going to become the FPS of the new generation, in other words, the safe formula to sell an unimaginative product.
Open World Games: Mirror's Edge, Dead Rising 3, Dying Light, The Crew, Tom Clancy's The Division, Metal Gear Solid V, The Witcher 3, Destiny, Assassin's Creed IV (Not sure about this. Is free roaming = open world?).
XBOX ONE & PLAYSTATION 4
The new generation it is here and to be honest it looks a lot like last gen but with shiny graphics and impressive big numbers like 1080p and 60fps.
Honestly I don't see any reason why I should be interested in any of the new gen consoles. Games? There is nothing really new there is all about shooter, zombies, racing and sports which is great but I already have it on the current gen. Graphics? I have a PC and I can get better graphics than this new gen so no, that is not a good reason for me. Social features? No, thanks. Kinnect and Playstation Eye? No. Motion controls? No.
WII U
Currently the worst console to own the Nintendo's machine showed a good selection of games tha are coming proving to everyone that it's future is not so dark as most think. With Super Smash, Mario Kart, X, Donkey Kong, Fire Emblem x Shin Megami Tensei and others I think that the Wii U will be something that I might buy for christmas next year(2014).
Playstation 3
For me it is right now the best platform to own. With Dark Souls II, Gran Turismo 6, Final Fantasy Lightning Returns, Final Fanatsy XIV, Killer is Dead, Dragon's Crown, The Puppeteer, Hohokum, Beyond: Two Souls, Doki-Doki Universe and a lot (really a lot) of other titles I think that the platform still has a lot to show and will probably keep me away from new gen for at least 2 years.
