In every year, I usually get one or two Mario games, but these are the specific ones I can remember.
2010: I was having a hard time, after having to leave 9th grade for medical reasons. I really wanted to actually go back to the high school, but my mother said there was a better high school, smaller and not anxiety-inducing. I told her I'd only do it if I got Super Mario Galaxy 2. She agreed.
Also, I fully subscribed to Nintendo Power after getting a few previous issues here and there.
2011: The 3DS released, but we couldn't get it yet. I don't remember much Mario-related things that happened otherwise.
2012: I got the 3DS for my birthday, along with Super Mario 3D Land. Wii U released, but we couldn't get it yet. Nintendo Power ended in December. I asked for Mario Kart 7 for Christmas, but my mom said she couldn't find it, and got Paper Mario: Sticker Star instead. The next day, Gamestop got a new shipment of Mario Kart 7 in. Hooray! This was really not a good year for me otherwise, so I've forgotten most of it...
2013: For my birthday, I got Luigi's Mansion: Dark Moon. My birthday was also Mario Party themed, with various Mario enemies to throw beanbags at, Star balloons, and marshmallow shooters. Also, Nintendo Force started and I've been subscribed to them ever since. I think I also got Donkey Kong Country Returns this year.
2014: On January 24th, I registered on a site I used a lot for Mario tips and information: the Super Mario Wiki (and Fire Emblem Wiki, the same day). After having to drop out of my senior year of high school in 2012, I was having trouble finding a place to really fit in. I never heard of an editable encyclopedic site (even after using the SMW and Wikipedia for years, I never knew you could edit it), so I thought it'd be fun. Truly a great decision that has led to many fun times

Also I got a Wii U in the summer, the bundle with Mario Kart 8. Got Super Smash Bros. for Nintendo 3DS and Wii U on their respective launch dates. amiibo turned into an obsession.
2015: I remember buying Super Mario Maker, and that's really it. I started being a bit more active on the Super Mario Wiki. RIP Iwata...
2016: March 27th was a... huge blow to the Super Mario Wiki community. I really wish I joined sooner, got to know Walkazo better, work with her on the staff team. I only talked to her a few times, she seemed like a great person, would've loved Super Mario Odyssey. Hope her family is doing alright.
2017: On April 17th, I got a message asking if I wanted to be a patroller for the Super Mario Wiki, which I eagerly accepted. Probably a little too eagerly ^^; It's something I was working toward, so I was happy to get the message. I learned a lot about responsibility and how communities work while on the staff team, and the community as a whole has been wonderful. While I'm still in the same rut now as I was back then, at least I have people to talk to. Thank you all.
Also the Switch released and I have yet to get one >_> This year is honestly a blur.
2018: Being more active in NIWA as a whole led to me getting promoted to a Super Mario Wiki administrator on my birthday. The decision kinda got rushed in order for the promotion to take place on April 3rd :p
I finally played a Switch. My Tri-Cities ARC community hosts game nights every now and then, and I was able to play Super Smash Bros. Ultimate late in December, along with Mario Tennis Aces and Mario Kart 8 Deluxe.
2019: I got Mario Party: Star Rush for my birthday, and Donkey Kong Country: Tropical Freeze during the summer.
Hopefully I can get a Switch for Christmas this year.
EDIT: Found someone selling their copy of the Mario Kart: Double Dash!! Bonus Disc, which is something I've been looking for forever!
