I got my switch last night with a Pro Controller. I freaken love this this thing. Zelda is amazing, already 4 hours in and I'm hooked. Obviously the pro controller is the way to go for long periods, but I also loved playing it for an hour in a handheld gaming style during my work break.
Everything on this system just feels elevated compared to the Wii U. The build quality feels more solid like theres more of a density to the hardware, the menu Ui is snappy and clean.
The only thing holding this system back is games, but I'm bullish on that considering the new direction they are taking with indie developers. The impression I have is that they are really starting to actually partner with a select, but expanding few indie developers to make their games get the most out of what the Switch can uniquely offer. Plus added to that is even if you aren't in that inner circle with Nintendo as an Indie, they have made the Dev Switch kits really cheap (like 500 bucks or something) compared to previous consoles, so it's now easier for indie teams to experiment with making stuff on it less of an investment.
The games I'm itching for to come out are Yooka-Laylee, Snake Pass, MK8 Deluxe (Just for the updated battle mode, finally arenas!!!), Street fighter 2 (so I can play it while travelling against my footy team while travelling on the road), Splatoon 2, Mario, Virtual Console games, and Wonder Boy: The Dragon's Trap HD remake.
