I recently bought Arkham Knight Ultimate Edition since it was the only one in the series I haven't played yet. While the gameplay lacks in some areas compared to the previous installments, the inclusion of the Batmobile brings it to a whole other level and makes it a great addition to this amazing series. Probably my favorite video game franchise.
I also bought Crash Team Racing, an updated version of the old classic racing game and it brings back so many memories. I'm enjoying playing both of these games a lot during isolation!
