I did this with Death Stranding a few weeks ago, and was trying to decide whether to continue and not know what was going on or just play from the start. But I ended up finding a playthrough from a streamer I like on Youtube, so I just watched those to get caught up.
Love it, would recommend to anybody. It’s got so much variety, I think anyone could find a game or two they love. I’ve got almost 150 hours in it, mostly on Party House and Campanella 2, which I’ve cherried but keep coming back to.
It’s fun to fire up every now and then and check out what’s new. I mostly play indie games, deckbuilders, etc., so I don’t care about graphics so much.
I will say they did monetization right - free to play with absolutely no pay to win elements.
I’d also recommend a book I checked out from the library recently, Emergent Tokyo, which goes into a lot of the same subjects and has some great insights.
80 Days - it’s not free but I think it’s worth it. It’s a sort of steampunk version of Around the World in 80 Days where you have to plan your routes, and buy and sell things in different cities to make money. The main gameplay is sort of choose-your-own-adventure events that happen during travel and in different cities.
Card Thief - I just started playing this recently. It does technically have a microtransaction but it’s more like, they let you play for free if you don’t mind waiting for chests to unlock, or you can buy the game to bypass this. The main gameplay is sneaking through dungeons represented by a 3x3 grid of cards randomly drawn from the deck; collecting treasures and avoiding getting caught.
I know this is an old post, but to answer the last question - to become a mod of an abandoned community, you generally need to message an instance administrator (in this case, @tedvdb) and request to be added as a mod.
