Is Tekken 5 and Tekken;Dark Resurrection the same game?

Question

These are 2 Tekken games, I have Tekken;Dark Resurrection but I want Tekken 5, I wanted to know if these 2 games were the same.

Answer 1

Not exactly...
Essentially, they both have the same engine. But DR has 2 extra characters (Dragunov and Lili)
A few more stages and backgrounds are added in DR (the stages from Tekken 5 are set at different times of the day)
Also extra costumes and extra moves in DR (pretty much an update)

Answer 2

Well, there's more characters on DR at the very least.
