If some think the pre-2008 content is compatible with the 2008-2014 content, I urge to have a look at Nathan P. Butler's timeline :

It explains clearly that you have to chose between the multimedia CW projet (CW cartoon,
Republic,...) and TCW because they are absolutely incompatible (and TCW is hardly compatible with the rest of the Legends and I don't found it coherent with the movies at some points).
Ok, there's the pre-May 2013 retcons but most of them are stupid and they do not cover everything.
And yes Filoni and TCW destroyed this period, while Leland Chee and others were trying to heal the wounds with retcons. I ignored TCW since the "movie" until they put me the nose in it in FotJ. Only last year I had the fortitude to watch the show... For me this belongs to the Story Group Canon and should have nothing to do with Legends, trying to integrate it into the former Expanded Universe was the biggest masquerade ever saw in SW history.
For the FotR, frankly I am far less interested in it than in ICW, so I wouldn't be much bothered if the dev team chose to go for the TCW version but that would be a little sad as, if so it will be close to a Story Group Canon view of this period and that's the actual trend. It would be better for the Legends to still live a little through mods such as ICW.
