I wrote to the seller via ebay, & he advised that he currently owns all three Avenger models, being the HULK LE, The BLUE LE and The Avengers PRO.
He stated he is keeping the HULK only and that he intentionally bought all 3 models to determine which one he likes the most, and therefore would keep.

IMO, the HULK is staying, the Blue LE is being flipped for a profit, and the Avengers Pro is being sold at a discount because he made some money on the Blu LE.
So it appears that its got nothing to do with not liking the game etc, but to do with his desire to try all the models out, and to keep or not to keep some for his business or personal reasons. The Avengers Pro does not come with full Leds either, only a few here n there, which is why the seller has added a full Led kit etc to make it look even better.
