But I believe it's still true that many will not work if they were designed for an older version of TOAW. The will have to be "fixed."
If you want 'quick and dirty' conversions, try this archive:
TOAW3 Legacy Packs Parts 1-42
This contains 415 scenarios converted by the “TOAW Legacy Project” and stored on the Game Squad File Depot in 42 separate files. I took the liberty of downloading them all, and then combining them in a single file for ease of downloading.
These are old scenarios from TOAW I/WOTY/II that were converted into the new TOAW3 engine so that you can play them again. The conversion process is totally mechanical and none of these scenarios have been modified in any way from the original. The conversion process itself is not perfect and so there will almost certainly be conversion errors. The most common ones are events being messed up, units with inappropriate icons, and, possibly map errors.
BTW; it appears that the Game Squad File Depot is now MIA. So I guess I was just in time last year in backing them up.
I saw generals create imaginary "masses of manoeuvre" with a crayon and dispose of enemy concentrations, that were on the ground and on the map, with an eraser. Who was I to criticise them, hero as I was of a hundred "Chinagraph wars" of make-believe?
