Yes, considering that aside from Skyrim with DLCs and mods, 90% of my gaming time has been on it for the last 3 years...
To be honest, i don't understand your adoration for the GBA. GBA in my opinion is the most overrated Nintendo handheld up to now.
If you exclude all the NES/SNES ports/remakes and the shovelware, what else did it have? A couple of Pokemon games, a Metroid game and a Zelda, a few Castlevanias and Megamans, 3-4 RPGs and what else? Even its unique and exclusives games were just spiritual SNES sequels in all but name...
The DS was exceptional, i'll give you that. In my opinion the best console, handheld or tv, of all time. Its gaming library was vast, with quality games in every genre imaginable... Too many unique games. A truly great handheld.
The 3DS, while not up to the DS's level, is still quite good for its first 4 years. Imagine the situation of the DS by end of 2008/early 2009. Many of the better DS games hadn't arrived by then.
It has a few exceptional games. In my opinion, Fire Emblem, Super Mario 3D Land, Mario Kart 7, the 3 Zeldas and the Monster Hunters are really good games in their respective genres. There are even more games in the "not excellent but very good category". At least 30 of them.
They are not many, and they are not the best games evah, but they are far better than anything else released after 2012. Seriously, what else is there? Assassin Creeds? The CODs? The Battlefields? The more movie-than-game TLoU? Tomb Raider? The Far Cries? What? Boring cookie-cutter AAA releases, unoptimized, full of bugs, and sold in pieces (DLC)? The "indie" games which are good for as long as the novelty lasts, about a couple of hours at most? "Challenging" trial and error waste-of-lifers like the Souls games? What?
