Ron Gilbert shares original Maniac Mansion design document

Legendary game designer Ron Gilbert has posted the original design document for Maniac Mansion, his seminal 1987 point-and-click adventure game that kicked off LucasArts’ golden age of adventure gaming.

Gilbert created the 14-page spec with artist Gary Winnick to articulate their ideas and build interest among their colleagues at LucasArts (at the time Lucasfilm Games). It’s a refreshing and fascinating look back at an earlier era in game development when creativity ran a bit more rampant without the limitations of huge budgets and focus-tested precedent.

There was no official pitch process or “green lighting” at Lucasfilm Games. The main purpose of this document would have been to pass around to the other members of the games group and get feedback and build excitement. I don’t remember a point where the game was “OK’d”. It felt that Gary and I just started working on it and assumed we could. It was just the two of us for a long time, so it’s not like we were using up company resources. Eventually David Fox would come on to help with SCUMM scripting.

Three people. The way games were meant to be made.

The SCUMM engine would go on to be the backbone of LucasArts’ most beloved adventure games, such as The Curse of Monkey Island, Day of the Tentacle, and Full Throttle. Gilbert outlines the engine’s basic operations in the document, dividing the screen between a picture of the action, a list of verbs, and an inventory.

The ideas laid out there would set important precedents not just for graphic adventure games, but the syntax of how we interact with games as a whole. The fact that he uses quotation marks around the word “clicking” when he describes using a mouse to select one of the characters on screen speaks to how wide and undefined the field was for ways that people could interact with games.

Simplistic as some of it may seem, it is also striking how little has changed in the nearly three decades since Gilbert wrote this design. The game’s interlocking system of puzzles, each with multiple solutions based on the particular combination of characters you choose to bring, leading to different endings based on who you brought and what transpired would sound right at home in contemporary games. In fact, it sounds more or less like what The Cave was trying to do. Moreover, the freewheeling process he describes feels very akin to the ethos of the current indie games renaissance.

The whole document is available on Gilbert’s blog. It’s quick and edifying read for the nostalgic, the curious, or anyone interested in the design process. He also posted a few pages of early design notes for The Curse of Monkey Island earlier this year, if you want more insight.

Full Pokémon list in 2025
Liko and Roy surrounded by Pokémon in key art for Pokémon Horizons: The Series.

The entire Pokémon empire was built on the simple catchphrase of "gotta catch 'em all." That was more than achievable in the first generation, but each one has added dozens upon dozens of new creatures to the roster. What started as a big, but manageable 151 Pokémon has multiplied by nearly a factor of 10 in 2025. It has gotten to the point where the newest Pokémon games aren't even able to include the entire roster anymore. Since we are obsessed with fully completing our Pokédexes in every game, we do appreciate not having an overwhelming number to deal with, but it does make it hard to keep track of exactly how many Pokémon there even are anymore. We have gone back through our old save files on every Pokémon game from the Game Boy to the Switch and counted every single Pokémon to give you the full list as of 2025.

How many Pokémon are there now?

Arc Raiders is fun, but I’m still doubtful about extraction shooters’ future
A player character in Arc Raiders.

I had a good time playing Arc Raiders at a preview event. So, why don't I feel like playing it again at launch?

Arc Raiders is the latest game attempting to stand out in the extraction shooter space. This shooter genre is very hardcore, tasking players with safely finding valuable loot across large levels and extracting before they can be killed. If players do die on a mission, they lose almost everything equipped to their character. It's a high-risk, high-reward that developers are treating as the next battle royale-like craze. Now, the developers of The Finals, Embark Studios, are entering into the space with Arc Raiders, a game they reworked to become an extraction shooter.

Borderlands 4

You don't have to wait long to dive back into the zany chaos of Borderlands 4 — Gearbox Software and 2K Games just announced the release date has been moved forward by two weeks to September 12, and that Sony will host a State of Play at 2 PM PT tomorrow dedicated entirely to the upcoming game.

According to the social media announcement, the State of Play will air at 2PM PT/5PM ET and feature "over 20 minutes of new weapons, abilities, missions, and more." Gearbox Software didn't provide a reason for moving up the release, but it did state that the decision comes after "careful consideration" and "a lot of meetings, playtesting, and incredible development work."
