Game: OpenTTD.
Owen Rudge, who released OpenTTD, writes that Ludvig Strigeus ("Ludde") had been working on a clone of Transport Tycoon Deluxe since 30 June 2002, and first told him about it by ICQ message in March 2003: a working version of the game, written in C, though incomplete. openttd-history/origins
paragraph 2Exactly 21 years ago, I received an ICQ message (look it up, kids) out of the blue from a guy named Ludvig Strigeus (nicknamed Ludde).Happy 20th birthday OpenTTD! · paragraph 5(He’d been working on it since 30th June 2002, so I guess that is technically the birthday of what would become OpenTTD…)Happy 20th birthday OpenTTD! · paragraph 7It was a fully functional version of Transport Tycoon Deluxe, written in C.Happy 20th birthday OpenTTD! · paragraph 8Admittedly incomplete at that time, it was still quite remarkable.Checked by claude, 2026-10-26 — read the post (dated 2024-03-06) in its pinned capture; "exactly 21 years ago" from that date is 6 March 2003Cited by: OpenTTD
Rudge recalls that in 2004 the Transport Tycoon community played Transport Tycoon Deluxe with Josef Drexler's TTDPatch, which had fundamental limits: the map size couldn't change, cargo types couldn't be added, and multiplayer was hard to improve. A clone in a high-level language, he writes, "got people very excited indeed". The OpenTTD wiki gives the same reason: the patch's way of changing the game made many features near impossible. openttd-history/why-a-remake
paragraph 9To put things in context, in 2004, the Transport Tycoon community generally enjoyed playing the classic Transport Tycoon Deluxe with the excellent TTDPatch started by Josef Drexler.Happy 20th birthday OpenTTD! · paragraph 11TTDPatch was an amazing piece of software, but there were always some fundamental limitations - the map size couldn’t be changed, extra cargo types couldn’t be added, multiplayer was difficult to improve, and so on.Happy 20th birthday OpenTTD! · paragraph 12So having an almost fully-functional clone of TTD, written in a high-level programming language, suddenly appear out of nowhere got people very excited indeed.OpenTTD Wiki — Manual · History of Transport Tycoon, "Enter OpenTTD"The Patch's method of modifying the game made a lot of potential features near-impossible.Checked by claude, 2026-10-26 — read the post and the wiki manual's history section in their pinned capturesCited by: OpenTTD
Rudge released OpenTTD 0.1 as open source on 6 March 2004, naming it himself, with a SourceForge project and a forum on TT-Forums. His release-day post calls it Ludde's "C reconstruction of TTD", 95% complete, and tells players to copy Transport Tycoon Deluxe's Windows graphics and sound file to run it. openttd-history/first-release
