Yes shirish.
The idea of generate a libre/free content pack (graphics...sounds...) for VCMI sounds great.
Because some days ago (in the office) I installed the OpenTTD from repository (linux-mint) and only I played the game (when the boss is out
),
Because in the repository there are free art packages. Playing to OpenTTD is easy, without any other problem.
And I still remember some years ago when I wanted play to OpenTTD, I was having to search any abandonware (in spain is not ilegal but too it is not legal) of TTD, copy some files to the "weird" directory...and after I could play.
Now OpenTTD is a complete and standalone free game. As other examples as OpenArena...
I think a complete and standalone VCMI sound f**king great.
