Personally, map mods have never really appealed to me (probably coz I'm just j'amn arse lazy ) but I reckon it's a cool feature to have just in case.
even FPS map makers have been very limited... my maps I've made on my fav FPS have all ended up as just.... rooms with guns.... that's about all there is available...me and my off-topickyness.. lol
Am I the only one to wonder how the Ice Climbers got into Super Smash Bros. Melee when they only appeared in one other game before that (discounting ports and Vs. Ice Climber), the original Ice Climbers for the NES? How did they luck out on that?
