1.53, 1.80g, 1.97 (1.96). I think.
The manual is a pdf and has been updated for TA with version 2.0, which is a free update via Impulse. Don't know if it has a print manual, or why it feels heavy, sorry.
UE is DL + DA + TA. Apart from the music CD, which I personally wasn't aware of until someone pointed it out, there's no real difference compared to buying the bundle package or buying the games separately (apart from cost, anyway).
