There is a simple question to ask yourself before buying this game:

Do you have a high resilience to bugs? ( Including having to reload A LOT to fix them )
If you do, then go ahead and buy this game right away. The amazing atmosphere and story is worth it even at this point.
There is a 10/10 core game here, that is just suffering from bugs and lack of polish in certain aspects.

If not, wait AT LEAST half a year until they fixed this mess and implemented some better systems. The Definitive Edition of this game will hopefully be absolutely incredible.

Anyway, see you in Night City choom.
