Can we please get more than 5 buildings to go into?

Ditto. Done that thousands of times. GTA IV is a great game, especially with the expansions. But there are a few annoying issues that should alsp be solved for GTA V.

Firstly, checkpoints. I know they were included in the first expansion, but I really do hope GTA V will have checkpoints, however frustrating missions can be. It saves you from having to drive back somewhere every time you fail.

Secondly, the airport needs to be more realistic. I know it's just a game and it's not too realistic anyway, but on GTA IV the airport looks amateurish. From a distance it looks like the planes are landing/taking off, but the planes just go round in circles, taxiing or "flying". I've looked at a "leaked" map of GTA V and one runway, for what looks to be the airport, should be fine.

Finally, the biggest annoyance in GTA IV is the traffic. Sometimes you just want to drive normally, stop at a red light... BANG! A taxi smashes up your backside as if you've stopped randomly on the motorway (highway). This needs to be fixed. Also, I don't see buses moving, they're always parked. That would be another good transport option.

Anyway, rant over. Let's hope these issues are fixed and GTA V will the best GTA to date, as well as Game of the Year.
