Is rainbow six siege still worth it (uplay offer)?

For 8 euro you get the deluxe edition with a 20% discount. Should I strike there? Otherwise, play bf4 on high in fhd on my mx150 laptop. Otherwise I have a workstation with rtx 2080 ti

You have to know that. For the price you can't complain under any circumstances

It's a good game, so yes

The division 2 is also available for 5-10 euro and is worth twice.

Definitely worth it.
