Cozy,
It's surprising that you ask this only as I've been contemplating authoring (or co-authoring) such a guideline for the last few months, but I've not pursued it because (a.) work's demands are ever-increasing, (b.) I'm still messing around with unit animations - refer
apolyton.net/forums/Forum29/HTML/000695.html , and (c.) the time I've spent has been focussed on either the 'topical design tips' that Paul's link will point you to (thanks Paul
), or improving my OCC score (still can't get a 19th Century victory!!!).
I think the process is largely the same however as traditional Civ2 scenarios. Ensure your game concept is reasonably sound, victory is possible but not probable, try to look for innovation in your design, and be prepared to be flexible during the process - the game you finish with will probably be a long way from your initial vision.
Test of Time does offer a lot of 'new frontier' sorts of opportunities for designers - things such as the collapsible technology tree, map travel, and masks (to name but a few) extend enormous possibilities to a creative mind!
Another great link is The Cradle of Civilization site, which has a focus on ToT...
civ.cx/ - many of the Design Tips are identical to the Scenario League's, however there are a few other tips, let alone the extensive facilities in other parts of the site - graphics, converters, scenarios, etc.
Oh, your question? No - such a guide for ToT doesn't yet exists to the best of my knowledge!
