If people fall for rumours, they're to blame themselves, not Nintendo. Listen to official statements and you're safe. Easy as that.

I wonder about the launches of the other two consoles: did people really expect Sony and MS to release all of their franchises at the same time? I don't think so.

I bought 7 games with my Xbox one on launch day 

3DS was the only time I bought a gaming device at launch, which was with only 1 game.

The point you're trying to make with the thread title question doesn't really matter, it's not like you're only allowed to buy launch games on launch day. It's about always having games to play. Having more games better ensures this'll be the case for more people. Of course it isn't reasonable to expect a fully fleshed out library on day one, but certainly more than 7 or so games is fair.

Me personally, I'm able to enjoy a variety of different types of games so the Switch line-up could be fine for me. The launch titles Zelda, Bomberman, and Setsuna should definitely last until Sonic Mania and Yooka Laylee, but I'm worried about from then til Splatoon 2 which I'm going with worst case scenario being August release. The only game inbetween to my knowledge is MK8 Deluxe which I'm not interested in. This probably wouldn't be a concern if there were more games available. Then again, it's not like my 3DS n Wii U exploded.

Just two, Zelda and bomberman. :D

Let's see.

When I imported the PSP months before EU launch, I also bought Gretzky NHL (pack-in), Ridge Racer, WipeOut Pure, Tiger Woods PGA Tour, Untold Legends and a few UMD-movies. The PSP had a good selection of titles at US and EU launch.

When I bought the Xbox 360 at launch day, I also bought Kameo: Elements of Power, Project Gotham Racing 3, Condemned: Criminal Origins, Perfect Dark Zero and Peter Jackson's King Kong; Dead or Alive 4 followed soon. Call of Duty 2, Gun, Need for Speed: Most Wanted and Quake 4 were also great launch titles, but I got these for PC. The Xbox 360 had the best launch game selection of a home console ever!

When I bought the Wii at launch day, I also bought Wii Sports (pack-in), Wii Play (pack-in), The Legend of Zelda: Twilight Princess and Rayman Raving Rabbids; Excite Truck followed a few months later.

The PS3 hadn't enough good titles (for me) at launch, so I waited a few months. I would have waited until its first holiday (Ratchet & Clank, Uncharted and Heavenly Sword), but I got an offer for the PS3 hardware I couldn't refuse (best phone contract ever!) before that. So when I got the PS3, I also bought MotorStorm, Resistance, PSN-Lemmings and some compatible PS2-games (f.e. God of War 2 and MGS3: Subsistance).

The 3DS launch game library was very disappointing to me, not one game appealed to me. So I waited.... and waited... until the 3DS-XL-launch, which fixed a lot of the first 3DS's flaws. When I bought the 3DS XL at its launch day, I only bought Super Mario 3D Land. New Super Mario Bros 2 and Professor Layton 5 followed a few months later. Ocarina of Time 3D and Mario Kart 7 were also very good first-year-titles, but I bought them much later.

When I bought the PS Vita at launch,  I also bought Rayman Origins, WipeOut 2048, Ridge Racer, Everybody's Golf, Escape Plan, MotorStorm RC, Mutant Blob Attack, Super Stardust Delta; I also won Uncharted: Golden Abyss, Little Deviants and Modnation Racers: Road Trip a week before launch and rented Lumines: Electronic Symphony, Ninja Gaiden Sigma Plus and Unit 13 soon after launch. The PS Vita had the best launch game selection of a handheld console ever!

The Wii U hadn't enough good titles (for me) at launch, so I waited over a year. When I bought it, I also bought Nintendo Land (pack-in), Super Mario 3D World, Donkey Kong Country: Tropical Freeze, Pikmin 3, New Super Mario/Luigi Bros. U and Zombi U; Mario Kart 8 + a free game (The Wind Waker HD) followed soon.

When I bought the PS4 at launch day, almost all games that interested me were delayed. :( So I sold it through with a nice profit. I would have canceled my order, but then I also would have lost my DriveClub pre-order for €20. When I bought my second PS4 three months later, I also bought Killzone: Shadow Fall (pack-in), Resogun and got a lot of nice small titles via Cross-Buy and PS+ until then; inFamous: Second Son followed soon.

The Xbox One hadn't enough good titles (for me) at launch, so I waited over a year. When I bought it, I also bought Sunset Overdrive, Halo: Master Chief Collection + ODST, Rare Replay and rented Forza Horizon 2. I would have also bought Ryse and Dead Rising 3, but I already bought them for PC. Forza 5 was also a great launch title, but I got it much later.

The only announced Switch-games in the launch window, that interest me, are The Legend of Zelda: Breath of the Wild (which I can get for my Wii U), Rime (which I will get for PS4 or PC) and Lego City Undercover (which I will get for PC). So I will at least wait for the release of Super Mario Odyssey, perhaps even longer.

Usually 2-3 games, + whatever it comes bundled with.

I usually don't buy consoles at launch.

But I was excited about X1 and I bought Forza 5, Ryse, DR3, CoD:Ghosts, BF4. None of it was amazing but I had fun with them all.

NES - 1
SNES - 2
Playstation - 2
Dreamcast - 4
Gamecube - 3
Playstation 2 - 1
Wii - 2
Xbox 360 - 4
WiiU - 2
Playstation 4 - 1

When the Scorpio Launches I will proberbly buy 10+ games since I missed a lot of the good games from MS over the last few years :)

I've never bough a console at launch, and probably never will. I have no problem waiting a while for the price to come down. When I do actually get the console I usually get anywhere between 1 and 5 games with it.

NES: 1
PS1: 5
PS2: 1
PS3: 1
PSP: 1
PS4: 4
