I think it's about as packaged as it ever will be. To play, just install fheroes2-demodata from application manager and then click the icon in the application menu, as you do with other programs. Everything is included. If you want the complete game to be packaged, you'd have to ask 3DO to make an N900 version for you. As it is now you have to copy the game data yourself as it is not free and thus can't be included in a package in the repositories. If you want the complete game installed all you have to do is copy the content from DATA and MAPS content to the correct places (/opt/fheroes2/files/data and /opt/fheroes2/files/maps) and it's ready to go. No config editing needed.
