After days of trying to figure out what to play, I randomly got idea to play old PS1 game that I finished countless times - Spider-Man 2: Enter Electro. It was nice trip down the memory lane. Finished it in two days on the hardest difficulty. I was struggling at the start, because I was getting used to controls, but after that it was pretty okay experience. I should probably play the first Spider-man soon too.
Anyway, to give Dawn some kind of feedback... I would love to see this event again next year. It made me try games that I probably wouldn't try otherwise like Super Mario 64 or Tales of Berseria.
Let me also give you my opinion on each theme:
Free Choice - Not much to say about this one. It's fine, but I usually didn't have to think about what game to pick. I just went with whatever I would play anyway.
Retro - This was one of my favourites. Not because there are tons of retro games I would love to play one day, but also because I found even more games thanks to other users. I wouldn't mind seeing this one more next year or even seeing the opposite - picking up modern game.
Spin-offs - Since I don't know many spin-offs, I had really hard time picking up game for this one. But I think it was fine theme.
RNG - I think this is a lot better version of Free Choice, because it at least makes me think about what games should I put on the list. I would love to see more RNG and less Free Choice next year.
Swords and Sorcery - Another of my favourites. This is exactly the type of theme I would love to see more. Take one aspect like swords, magic or guns that can be applied to several genres.
JRPGs - Another of themes I would love to see more. Similar to Swords and Sorcery, but now allowing only specific (sub)genre. I wouldn't mind seeing more (sub)genres like Souls-like or Survival theme for example.
The Pacifist - Same as Swords and Sorcery.
Modern Warfare - Same as Swords and Sorcery.
Spooktober - Same as JRPGs.
Visual Novels - Same as JRPGs.
Hard Mode - Same as Swords and Sorcery.
I've been also thinking about some themes - Male/Female-led game, game from the year you were born, game from the year you joined PC, Medieval-themed game (or basically any historical period), Survival game, Racing game and more genres.
