Before: The first released next-gen console, that has to be worth something, right? Eh, possibly not considering how little of a selection of launch titles it came with: those being ZombiU and NintendoLand. With not much third party support for the tablet console it doesn't seem worth too much aside from the backwards compatibility, but even with that it isn't much of an upgrade. The only hype behind getting the console was Pikmin 3, which isn't a large base to build from.
After: Okay, now we're getting some third party support. Deus Ex Human Revolution and Watch Dogs in more specific, alongside with some Rayman Legends. Nintendo also built up more hype games behind it with the inevitable reveal of Super Smash Bros. Sadly no details of Pikmin 3 during their conference (Yes, they did post a trailer after the conference). But the question remains after these games release: will the hype be enough? We'll have to wait and see.
After: Nope. Nope, they did not do any better at E3. That rape joke especially was not any better. The games are still unappealing; aside from Titanfall and Metal Gear Solid 5. But those few games will more than likely be released to different platforms. Minecraft is also getting a release for the One and even though I didn't have an appeal towards it on the 360, I still don't now. Speaking of the conference, why would you give your old console a redesign while attempting to hype a new one? Unless they know they made a bad move which was getting more evident by the minute.
After: Holy crap, they stomped Microsoft, hard. Aside from dancing on graves, they actually showed off a lot of games that actually made me want to buy the console. Watch Dogs, Don't Starve, Destiny, Warframe, Transistor, Kingdom Hearts 3. They just rocked that entire conference honestly. Even Infamous: Second Son looked really good and I don't really care for the series. Visually, they did amazing but can they do it game play wise? We'll have to wait until this holiday season to find that one out.
