After few weeks delay this one is finally finished.
As usual i did go overboard, then again this is scene not an asset,
so remove stuff you don't like (there's always alt scene). 
Overall changes:
-all ramaining atoms linked to "_room_link_cube"
-renamed all remaining atoms (not possible to mergeScene with previous versions)
-renamed and changed custom textures to load from RVU.Dependencies
(previously created scenes will miss textures if using latest.package dependency)
-added 2 alt scenes:
--Basement_Empty (no furniture)
--Basement_Alt (no furniture, no sounds, no outside light, no outside environment)
Environment/Outside changes:
added toggle for skybox
added toggle for env.light (directional)
added toggle for glass (windows)
added reset for window APs
added fake glass (cube) +toggle (fps alternative)
added glass tint (wall) +toggle
added env.sound +toggle +volume control
improved power fuse/breaker box
reworked button switch wiring
added basic "plumming" pipe
Lights/Lamps changes:
added toggle for lamp "cover"
added lamp buzz sound +toggle
added lamp flicker sound +volumesync +toggle
added 2x toggle APs for each lamp (to prevent out-of-sync spamming)
added main light AP (start order)
added manual toggle/reset for each lamp (to fix sync/intensity after flicker off)
added button toggle for upstairs light
tweaked all invisible lights atoms
Staircase changes:
added 1k wood textures
tweaked colors
lowered each step height
raised handrail height
Furniture changes:
reworked/tweaked all furniture placement and settings (VAM themed)
added shelves with random junk
added AptSmartTV with basic song picker AP (8songs/manual pick)
added ping-pong table (for lulz)
plus some other minor changes here and there....
Now for creators that used my previous_wip scene and don't wanna go through hassle of porting entire scene (since MergeScene is not possible due to atom renames).
a) edit dependency for this package from "latest" to v1/v2 (depending what version scene was based on)
"dependencies" : { "RVU.Basement.latest" :
--> "RVU.Basement.2"
or "RVU.Basement.1"
b)"more reasonable" route (for end users, less dupes) update all 18 "wall" atoms inside your scene with correct texture path to RVU.Dependencies.latest (in total 36 edits)
