So many games have seasonal events for Halloween. Typically it's multiplayer focused games, mobile games, MMOs, and simulation games. Are you participating in any right now? If so, which ones? I played a little bit of the Halloween themed Splatoon 2 Splatfest this weekend. The theme was Team Trick vs. Team Treat. It was really cute and they gave out special Halloween gear and the Inkopolis Square and some of the stages were all decorated and the ink colors seemed to glow.
I liked the Pokémon XY event, were you could get a Super Size Pumpkaboo with the Trick-Or-Treat attack. Shortly after that a tourmanent got announced where you could only use ghost types.
I participated in FFXIV's annual All Saints' Wake this year. =') Was a load of fun! Not tedious or time-consuming at all either, which is great for someone like me who's busy. Got both minions with very little effort. ♡ Should probably do another dungeon run or two for those decorations before it ends though, haha.
Right now I'm playing Dragalia Lost,and they have a Halloween event going on. It's an alright event, but the previous one was much better
I've participated in FFXIV's Halloween event, All Saints' Wake, and Monster Hunter World's Halloween event, I do like these kind of events especially if items from previous ones are still available for purchase or can be gotten from playing the newest event should you have missed it or are new and haven't been around for the other events. Neither of these were grindy the FFXIV one was 2 runs to get what I wanted.
