What games are you thinking of getting? I'd personally recommend:
Dark Souls 3: This game is lots of fun with a great story line. Only downside is once you start playing, you might catch a case of insomnia and find yourself not eating for hours. Honestly it's definitely worth a buy!
Tekken Tag Tournament 2: Because it's a great fighting game to play both at a casual and competitive level. It's button mash friendly but can be more difficult at a more expert level.
Call of Duty BO3: It took me a while to get good at this game but it was worth it when I did. Ever just wanted to style on dudes while you kill em? Well you can in this game. Halo meets classic Call of Duty. You can choose from a number of specially trained characters with unique abilities to play with. There's a character that rocks a grenade launcher, another that can turn invisible and my personal favorite 'Outrider' who fires explosive arrows from any distance. Just give her a target and she's got you
