The jam theme was A Small World. 38th Century is a simple world simulation game. When a century is up, use the clues you noticed every decade to make the best investment for the century ahead (in one of defense, health care, industry, or science). If your prediction was correct, your population will be sheltered from the inevitable disasters that strike every 100 years.
Took 72h this time, but still had to cut a lot of the content and features I planned to include. Spent the first day designing instead of jumping straight into programming. Did better at reusing code from older games, and tying this into a game with a beginning and an end.
Every participant was assigned a random theme, mine was Church 2.
This was the first time I used the Entity-Component-System architecture that I've been working into my game engine. Got a little more done than at Ludum Dare 36, but all you can really do is walk on the map and trigger some events. Spent way too much time drawing the cathedral!
The jam's theme was Ancient Technology. A CGA-style game (320x220 in 4-color mode) where you travel back in time to annoy a Stegosaurus. Gameplay inspired by the classic Moon Patrol.
This was my first 48h game jam, learned first-hand how short that really is :-) It was also my engine's first new project test in years, so this game attempt lead to a lot of improvements down the line.
