I would say this is how Skyrim vanilla should have been about 5 years back, the 64 bit and DX11.
Most of you may probably say "there is nothing new...same old same" etc.
The release of SSE was not about bringing new game but fixing exactly what everyone was complaining about - CTD, 32 bit, better visuals and nothing more. There was never a single promise about a new game or new graphics, simply set we've got what we exactly asked, a 64 bit and that's working so far flawless after running 24 hours on my 5-year-old PC.
When anyone attempts to compare modded old Skyrim vs. new SE version, please keep in mind this is an unfair comparison and if you truly need to compare you should load vanilla vs vanilla.
And here are some answers for upcoming modding for new SSE and Dem mods.
Q: There is no SKSE and no SkyUI and all mods dependent on SKSE. I need my SKSE back and refuse to play this vanilla sh$t. Where is my SKSE?
A: SKSE team is already working on creating a 64-bit version of DLL, however, they do not have any promise when it will be released. Once it is out to the public the dependant mods would be updated by mod authors if they are willing to do so. If not you are welcome to update mod using new CK64, the process should be simple for experienced modders. one caveat you can't release the updates since you are not the mod author.
Q:Are old LB/DEM mods will be converted to SE?
A: Based on Krista answers on modgamers forum, probably yes, but only after the CK64 is released (
Q: Would be DEM for SSE translated as it was with old Skyrim?
A: Sure, you should expect newly translated ESP files once the original are available.
All newly translated files of old mods will be hosted on original mod posts and all newly created mods will host new translation respectively.
Just remember, fully modded Skyrim as we have it now was not created overnight on 11/12/2011, it took many years and sleepless nights by a horde of modders to make and fix Skyrim look and feel. Now we have a much better platform and also let's not forget most of our favorite mods can be easily converted if original authors would do the job or pass it on to another modder.
