@Stretchedwiener @GurneyJourney But they are cool toys!
@MjTheHunter Map it before implementing or even designing anything. Identify stocks, flows, verbs, tokens. Sketch it in a diagram. Then you should be able to see how you can decompose it into subgraphs. Then it becomes tractable. THEN you prototype.
[noclip EARLY ACCESS] How the Jedi Took Down Star Wars Galaxies We speak to iconic game designer Raph Koster about the design of Star Wars Galaxies and the “Jedi Problem” that contributed to the MMO’s downfall. patreon.com/posts/15828105…
@osamadorias Haha, ironically I just did this exact design task over the last two days!
@DamonWilkinso11 @_Floura_ UO is where they were basically invented. Pet systems in earlier games were limited to summoned elementals mostly. Crafting as we know it today was essentially introduced into videogames in UO.
@_Floura_ That said, though, Theory of Fun has nothing about UO in it. For that you want my other book Postmortems. :)
@_Floura_ There are episodes of the first season of the anime which are directly drawn from specific bugs and features in UO. The player killing in town was taken right from the game. So was much of the peaceful play: cooking, housing, and fishing. UO pioneered those in MMOs.
As usual I have signed all the copies of my books at the @Official_GDC bookstore!
@Stretchedwiener The context of the original quote is that the game system didn’t make you cry, the story did. We’ve known for centuries that stories can make you cry. ;)
@MadisonRaeGun I’m trying to bring back the vibe with Stars Reach!
@liminal_warmth @rebelempiricist Well, some have. But yeah, this is very much not a hot take… but there’s this odd perception I’ve seen esp on Reddit that WoW classic and EQ are sandboxes, that WoW was a small scrappy project (!)… so I get where you are coming from.
@RGTreasure All depends on scheduling… can you drop me a line via my website maybe?
Recommended posts, 2017-2025: It's been over five years since the last time I gathered up recommended posts in one place and added them to the menu above. I figured I was due. As usual this will include talks and interviews as well as articles. raphkoster.com/2025/11/26/rec…
JustaMirage has once again impressed the dev team with his construction of a helicopter.
My last and final tweet <3 telegra.ph/The-last-messa…
@akspad I have become convinced that if you are an inhabitant of a preferential attachment network, you only ever want to live in ones with a certain degree of connectivity. Put another way: flat or steep power laws both suck to live in. Midrange is best. :)
Interesting read by @raphkoster - a practical example of when a power law can be detrimental to an otherwise reasonable system. raphkoster.com/2017/09/22/310…
Today I came across a project that rebuilt all of Tatooine from SWG in VRChat, and another that is recreating all of UO as a Valheim mod. Kind of wild to see.
