Well then: yay for upgraded DeadLands! ^^
But also: if you want real help then launch your ZKL and join #zkdev chat, where a couple of mapmakers that ZK has as well as some general spring ones reside.
Oh while at that I would also like to see you play more of... Zero-K. Because you know: it is hard to develop for a game you have barely played at all :F
Speaking of your issue with base of features:
http://springrts.com/phpbb/viewtopic.php?f=56&t=4047http://springrts.com/phpbb/viewtopic.php?f=56&t=22943Features added well give flavour. Features added badly break pathing, game balance and make the map unplayable.
For bad examples look up Tournament Desert and Oasis. First map has 2 bulky features wich break pathing. Second has undestructible cacti that vechicles get stuck on.
For good example look up Ravaged and its ruch flavour of features: and they dont even give any reclaim! Speaking of wich: Ravaged is one of the best Spring map technically wise and one of the best aesthetic wise. The only major thing it lacks is that it has SMD instead of mapinfo.lua
So one last thing is that I would like to request you to switching into mapinfo.lua since it is superior config file over SMD (it is just more flexible).
Good luck :)
