ok Toddel...
Started "leveldesign" in 1988 writing "pen n paper" missions/adventures etc for friends (yes I'm old) with maps etc to it, stopped that sometime in the beginning of the 90's though..
Started in 1999 making some levels for CS, dont know what version it was, didn't care either as I didn't like the game, however I got a taste for leveldesign by using their Editor "WorldCraft".
In 2002 bf42 came and I haven't really played a lot of other games except bf42, RtR, swoWW2, BFV etc since then (apart from some singleplayer games, and ofcourse Operation Flashpoint!).
Anyway in bf42 I started vanilla custom mapping immediately, moved to BFV in 2004 for some more maps, and made an infantry mod called "BFV Grunts", later moved to bf42 InfantryMod making "Infantry Mappack", then almost 3 years ago joined Forgotten Honor as I considered bf42 vanilla and all other mods dead, and/or irrelevant.. (except EoD which has one of my maps "Deserters Island").
In any case FHT was the place to learn advanced mapping, as you work with "live" players, in a team...(with very clear design/goal/purpose, something that "freelance" mappers dont have, which is the reason free-hand mapping is difficult in Battlefield games... making maps is not hard - finding or creating a context for where they should be used is the hard part, remember that!) made many maps there, released "Lost Soldiers" mappack, later on also the Expansion to FH1 "Forgotten Honor Mod". Then entered FH2 about a year ago and am now working on Normandy.
Simultaneously Im taking a GameDesign program, learning, well design which is pretty much "how to make a game" incl 3D art, project-leading etc etc etc...(a game is a lot harder to make than you think) Hopefully it will lead to work. The end.
