If you're on last gen, pass, simple as is. The performance on last gen isn't worth the 70€ price tag. If you play on a PC that can handle it you might consider buying it, they already made the game more stable all the bugs I've encountered thus far weren't game breaking, just hilarous. Also it's not as full of bugs as people say, I'm almost 30 hours in and the only bug that actually negatively affected me was a single mission that was broken for me but that was fixed by reloading a save from earlier.
Imo, it's best to wait for a stable and patched game that may even drop in price but if you're curious and not on last gen consoles you may give it a try.
