Seems like mostly a low-cost, promotional gimmick for Wonderlands to me. If I had Epic I would download it for free and play, just to see the minor changes. But I don’t. If it was rebuilt in the BL3 engine, I would spend the $10 to get it on Steam and play to re-experience the original story with up to date mechanics. But they didn’t. Missed opportunity there, I would say. What better way to hype people for the new Wonderlands than to rebuild the proven campaign in the BL3 engine and introduce the new Wonderlands mechanics?
In any event, if the intent was to get all the old BL2 players interested in Wonderlands, GBX should have released this one shot for free for anyone who already has TTAODK. As it stands, I see no added value worth the money they are asking so I have no intention of purchasing it. At best, this release might prompt me to fire up BL2 and replay TTAODK again. But even then not likely anytime soon. Maybe when Wonderlands is almost ready to launch (or more to the point, when Wonderlands is on sale). But for now, I am looking forward to the 10th Anniversary Skyrim Edition in two days. That I am willing to pay money for. In the meantime, I am (re)playing Fallout 4 and having a blast (sometimes literally).
