Only if BoD is in an acceptable technical state by now, it can seriously be compared to Demonicon. At release it was just not playable.
Assuming that BoD is playable by now, it's very difficult to compare these 2 games. The original BoD was released more than 20 years ago and has a gameplay you won't see in any game today.
For example upon starting the game (after creating your party of 6 chars) you just start in a town with nothing to do. No quest, no problem, nothing. Another thing is you can just die on your travels due to lack of food or clothing.
If you're open minded and want to try something new, give BoD a try (as soon as it reaches an acceptable technical state).
