As far as a wishlist goes I don't want or expect anything radically different. What I really want is to improve the current version of Forge we have. This isn't Farcry, we don't need a full on terrain editor because that's just never what Forge has been about. This is of course only my opinion and may not reflect everyone's. I am a forger, not a modder or a competitive player. My wishlist will mainly be things that pertain to forge on a visual level.
I'm going to do this fairly roughly. Bulletpoint style. Will edit later.
-Complete variety of canvases with no prebuilt structures (Snow, desert, dirt, grass)
-No invisible walls on objects
-Remove "Reset Orientation"
-Add group copy/group save/group paste ability for objects
-Bring back precision editing and zoom
-Keep building blocks but expand into larger sizes and make the textures simple and/or customizable
-Fix the "Pieces Shifting" problem caused by 2 or more people forging.
-Obviously more budget
-More decorative pieces (railings, windows, doors, antennas, crates etc.)
-Sizable invisible walls
-Give us an "undo" button
-Let us forge underwater again
-Traitzones that actually function and can be adjusted to specific teams
-Mancannons that actually work the same way everytime you use them
-Large terrain pieces for easy height variation (e.g. Large hills that match the terrain of it's corresponding canvas)
-Large walls that can blend together (No textures, make those customizable)
-The ability to change atmosphere (Time of day, lighting, water level, fog etc.)
-Dynamic objects (Moving objects, breakable objects)
-Sound emmiters
-Make respawn and despawn timers adjustable from 0-999 seconds on all objects
-Visual decals on pieces (Blood splatter, dirt, rust, corrosion, cracks, customizable text, colors etc.)
-Adjustable areas of particle effects (Spores, sparks, fire, falling snow, smog, precipitation, gases etc.) [These should have no effect on a spartan, we will do that ourselves with trait zones]
-Get rid of premade buildings, if you want to attract casual forgers, make it easy for them to link together blocks and ramps, not premade buildings
-Do not limit pieces by how many are in each category, instead measure and limit it by performance on the engine
