Most of the stuff I've posted here and in the other thread should work with FW (I used MGE to test the non-ToT events but I'm pretty sure the FW macro is exactly the same).
Also is the any correlation between the quality of scens and their chance to go to Downloads?????
I already tried to submit few scens a month ago and they aren't here!!!
Yes. The reasoning is that Civ2 has been out for a while now and a higher level of sophisticaton is expected (for new modders, it's assumed that they don't have to start from scratch--as modders did when Civ2 first came out--as there are plenty of good examples that they can learn from).
In your case, I'd suggest elaborating on what you're already doing: more detail in events.
OTHER STUFF:
Graphics: If you're designing you're own stuff then it should be good (no doodles: note that in Civ3 there can be over a hundred frames to each unit animation--the equivilant of drawing a unit 100 times!). If you're using other people's graphics, don't just pick the ones you like, pick graphics that are similar (i.e. look like they go with the same scen--that is, your scen; for God's sake, make them proportional in size.). Also, don't forget to give credit. One thing you can do is to take an existing unit as a template and edit it to suit your needs--you don't have to give credit for that if you change it a lot (but if you do, also indicate that you changed it).
I would also suggest putting some time into terrain and other graphics; you can also in this case, I would suggest taking from existing scens as terrain can be more difficult to design than units as it tends to be more 'realistic.'
(Note: making the terrain lighter and the units darker makes it easier for the player to spot units--i.e. there's more contrast so the units show up more on the map.)
Sound: Not a big one because it takes up a lot of memory and has no effect on gameplay but it adds atmosphere.
Scenario (i.e. map, unit/city/improvment placement): Make it clean. Avoid making the scen look crowded. Likewise, avoid making it look too boring with too much room to do too little. Don't place too many unecessary units on the map as this makes the first turn a pain in the a$$ for the player--you can always add more units later via Events.
Gameplay: This is what ulitmately determines whether your scen is good or not; I've seen scens that are very historically detailed but are just a bore to play. Events can really make a scen more interesting (e.g. I've taken scens that had potential but lacked good gameplay, added a whole bunch of events and made the scen way more fun). Generally speaking, more is not usually better in Civ2 scens. The exception is events: the more events you have (not just repetitions, I mean variety of events), the more interesting your scen will be--as long as they make sense; don't just add them as an afterthought but rather as a key function of the scen (this is especially so if you're designing an RPG-style scen).
Oh and remember to test for bugs--nothing ruins the scen for others than playing halfway only to have the game crash. Playtesting is ABSOLUTELY ESSENTIAL; it's really irritating when people create a scen and post it without having even played it through themselves (getting others to playtest is ONLY for gameplay purposes--don't make them waste their time doing work you should have done yourself). (Note: be careful with the tech tree, it's the most common source of scen-related crashes.)
If you do all that and, if possible, innovate on already existing stuff then I don't see why your scen wouldn't get added. If you have any concerns, contact Duke (mod). (Note that you have to contact the mods in order to get your scen announced on the main page.)
BTW, if you want more info on scenario design, just ask and people here will be only too pleased to provide you with links to relevant sources.

If you want help with a specific event, post it here (or the other thread if you want) and I or someone else will try to help.
