I'm probably going to pre-order GTA 6 sometime this week because preloading is already available and I don't want to be trying to download the same 200gb game at the same time as hundreds of millions of other people. I'm sure the servers can handle it, but I'd still feel better just downloading earlier. I'd like to be completely sure that I'll be ready to start playing after work on Thursday, and I'll feel more confident in that if I already have it downloaded in advance.
