I wasn't collecting when the SOTE stuff was hitting, but it sounds like it wasn't exactly a big hit at retail or with collectors.
To say the least, and it just hasn't aged well. They were actually the first "Collection 2" assortment that Kenner/Hasbro did, and because of that, a lot of cases were ordered by retailers (new assortment number = more ordering, I guess). Half of the case was characters nobody knew (Surrogate Han Solo and the Creepy Pheremone Monster) or characters in Punk Rock or Power Rangers get-ups (Snoova Vicious and the Wookiee Pistols alongside the Red Starfaced Ranger). This was filled out with three much-requested at the time versions of the main characters (Jedi Luke, Leia Boussh, and Carbonite Han; all of which would see reissue the following year on green cards) and more Yodas and TIE Pilots.
This was also in the age of 16 figure cases, so there were four more slots of sucking action than we have these days (imagine TSC Palpatine packed at 4 per case...shudder). Leia, Luke Jedi, Han, and Yoda sold quickly, the TIE Pilot sold well, and stores had walls of Lizard Hefner and Faux Solo and Snoova. It was so bad that a friend of mine bought a veritable ****load (and trust me, the figure was a piece of ****) of Xixors on WM clearance for a dollar each and would send them to his "friends" as a joke.
Add to that the fact that the sculpts are waaaaaaay dated now, and the fact that SOTE is a rather horrible book (I can anticipate the flames for that one, and I know I'm something of an anti-EU person, but the writing was awful, especially considering it was supposed to be this massive media event), and you've got a line that failed miserably when it was released and who not many people have much fondness for (at least merchandise-wise) at this point 10 years later.
As I haven't and won't pay for website access, I don't know the first thing about the video game in question for next year, but Hasbro needs to tread lightly if they're planning on making a new video game with unfamiliar characters the central focus for a large part of the year's merchandising, especially in the 30th Anniversary year when, IMHO, the focus should be on the SW we know and not the SW we aren't familiar with.
