Here’s a provisional list (caveat: I’m not an organiser for any of these events, so no guarantees):
Finished IntroComp games allowed:
ParserComp: ParserComp 2023 - itch.io
Can I enter the full version of a game I entered into IntroComp?
You can submit:
You may use your own seed from Round 1.
(Although if you don’t combine it with someone else’s, you won’t be eligible for awards. I assume that means one couldn’t enter the IntroComp version as a seed and then finish it for the sprouting round and remain eligible, unless one also used another seed?)
Spring Thing: Spring Thing Festival of Interactive Fiction
A translation of a game from another language or an extensively fleshed out version of a game prototyped in IntroComp or Ludum Dare would probably be cool; a minor improvement to an already existing game, not so much.
Finished IntroComp games not allowed:
Adventure Jam: Adventure Jam 2023 - itch.io
Constructing the game itself is not allowed until the beginning of the jam date.
(I assume that this also applies to constructing an introduction or excerpt, since those are parts of the game.)
IFComp: The Interactive Fiction Competition
I have an unfinished game people have already played. Can I finish it and enter it into the competition?
It all depends on whether or not the game’s earlier version has been released to the public.
[…] if the game was available on the public internet, where anyone could find and play it, then the IFComp considers that a release – even if the game wasn’t finished yet.
Can I enter a game that I’ve already shown at festivals or other events?
Every IFComp entry should be, in essence, the world premiere of that work. If you’ve already shown the work, whether in current or earlier form, in other festivals or competitions, then IFComp considers it an already-released work and therefore disqualified from entry.
Finished IntroComp games presumably not allowed:
Some of these have a “jam character” (similar to the Adventure Jam above), where the spirit (if not the letter of the rules) is to produce the game during the event. Others might allow starting beforehand, but require new games.
The organisers might count an extensively expanded IntroComp entry as an entirely different and therefore “new enough” game for the purposes of their respective events, that’s why I put them under “presumably”.
EctoComp: ECTOCOMP 2022 (English) - itch.io
The games should be original and previously unpublished. With the exception of localisations of previously unreleased games in the current competition language.
inkJam: inkJam 2022 - itch.io
Is there a theme? Yes, and it will be announced as soon as the jam begins.
(On the one hand, the page doesn’t mention anything about a requirement for new games at all.
On the other hand, it is a themed jam, which usually conveys the idea that the majority of work should be done during the event itself. And it runs for only three days, so entering a massively extended version of an IntroComp game doesn’t seem in the spirit of the event.)
PunyJam: PunyJam #3 - itch.io
The game must be new.
[Entrants] may not publish compiled versions of the game publicly before voting starts.
(This is also a themed event.)
Text Adventure Literacy Project/Jam (TALP/J): Text Adventure Literacy Jam 2023 - itch.io
The game must be an original work that has not been previously published.
Neither the source code nor the story file or executable can be published in a public place prior to the submission closing date. You can send the game to testers, but this must not be done in a public forum.
(EDIT: but see Garry’s post above: IntroComp 2023 - #15 by Warrigal)
Winter TADS/ZIL Jam: Winter 2023 TADS (and Dialog, Punyinform and Zil) Jam - itch.io
The game must be new.
Compiled versions of the game should not be published publicly prior to the start of voting.
