My poor old Xbox really doesn't like these newer games with their large file sizes - GTA V is nearly 8GB, CoD: Ghosts is 2GB. My hard drive is only 20GB as it was one of the first models, so I keep having to delete old save files from old games. A bit annoying - I'll have to invest in a larger hard drive and transfer it over.
Played the first few missions on Ghosts and you'll be ASTONISHED to hear that it's standard CoD. The only new feature is the use of the dog to help with stealth missions, but it's just like using a RC-XD in previous games so even that's not exactly cutting edge. It is slightly better than the last few games but the standard linear gameplay of 'follow the NPC', mega-explosions, totally OTT and wholly confusing plot are the same as ever.
I wasn't really expecting anything else though, it's multiplayer that I'm anticipating the most, same as ever.
