2. The reason some vehicles in H3 don't have side weapons is because they didn't have any in the first games. Vehicles are designed as a meeting point, which force players to work together, both to use and defeat enemies using.

3. Huge maps are far less fun than maps where you're able to reach anyone around you quickly. A real person can't run that far that fast, but real people can't stand being shot up to their heads in the ground, either. It doesn't claim anywhere to be completely realistic.

1. Spawn killing can easily be fixed by the makers of the game by fixing the level where you can only spawn in your base away from any enemy. The spawn zones also must be in a safe area where no one can snipe into. Halo 3, for the most part, qualifies with both of those and spawn kills are pretty rare (compared to other games, e.g. COD4).

2. The reason some vehicles in Halo 3 have side seats without any cool features is to make them less powerful. If you make a 4-person vehicle where everyone has machine guns, it'll shred through any opposing infantry becoming an instant powerhouse and changing the gameplay to being unbalanced. Halo also tries to focus fights down to 1on1, 2on1, or 2on2 situations that don't involve outside influences like vehicles.

3. Huge maps are purposefully made to be just that… HUGE. Battlefield 2 is trying to replicate a real-life battlefield. A real person could not just run all the way across in a matter of seconds. That's the point of the map…

1. You can choose where you spawn.
2. The passenger can shoot the guns in a vehicle.
3. You can run super fast.

So nothing special here. Sorrry.

Please put more points into writing next time.

My good sir you have been misinformed, or are blissfully unaware of what you're doing.
