if Gui gets to put Katamari on his list then I get to put Freedom Planet on mine because that came out on switch in 2018!
All kidding aside, it's always fun to hear these sorts of things. honestly, 2018 was a weird time where I've done a lot of gaming, but it was moreso concentrated in a few spots rather than a chance to sample a lot of games. According to steam, I'm up to 1847 hours in Final Fantasy XIV. granted, some of that has been AFK idling, but MAN has Eorzea sucked me into it's gaping maw like Fortenite absorbed Jon.
I don't even think I purchased a retail switch game until Octopath Traveler. granted, I loved the dickens out of that game, but something happened where where Octopath Traveler and Syrenne divided by zero and simultaneously killed my desire to play my Nintendo Switch and listen to Radio Free Nintendo for a good several months. maybe it was also that 2018 has been one of the roughest patches in my life as well...
I feel like Bloodstained: Curse of the Moon needs a nod. it may actually be one of my favorite Inti-creates games I've ever played, and I'd play it again over the likes of Castlevania 3 at any oppertunity.
Super Smash Bros. Ultimate has been a strange journey for me.World of Light and it's highly symbolic and allegorical narrative had me stop and question the nature of something that I always think of as the celebration of... well, at this point, I think it's safe to assume "all of japanese gaming" is an apt description of Super Smash Bros. now. I feel a strange and somber feeling come over me whenever I play the game. I don't know what else can be said about it that hasn't been beaten to death by the rest of the internet or that woulnd't start a nuclear flame war in the comments here.
Mega Man 11 exists and isn't even the best Mega Man game I played this year. it did make me consider some things I should and should not do in a little game dev project I did work on during 2018?
and then... I know I sent an e-mail having a small existential crisis over this, but... then there's La Mulana 2, a game that does SO much right in my book, but then also does things that I cannot excuse. as of the writing of this forum comment, La Mulana 2 ver. 1.4.4.2 is still the current version of La Mulana 2, and it is a broken version of La Mulana 2 where you can soft lock he game in an area with a save point that you are more than likely to use. I did this to my save file 39 hours in, and had to look up a trick to revert my version of the game to a previous patch via use of the steam console in order to fix a bug that has been reported to the devs for the past 3 months now and there has been no hot-fix.
I suppose I finally played Undertale this year, and... it's all right? I still have a LOT of problems with it, but I cannot deny some of it's qualities.
Deltarune is immediately a better game, and it's literally just a free demo, sooooo....
I started playing and Dropped Final Fantasy XV Windows Edition! that came out in 2018... I guess... maybe...
otherwise, everything I can think of that i played this year was either a fan game of some sort, a Doom WAD, or Rivals of Aether, which isn't a 2018 game but had some relavent 2018 DLC.
