Lets consider the fact that ODST is an open world game.
What does this mean to us?
It means that on the day ODST comes out, there are going to be many of us who will go home, boot up the game, play for a bit, then sit down and cry.
Why, you ask?
Ive already stated the answer.
ODST is an open world game. Most people dont realize what this means. This means that people will have to learn restraint. The average Halo 3 player burns through ammo and vehicles like diahrea does toliet paper. They know, that either theres going to be ammo and new warthogs at the next checkpoint, or you can always jump off the nearst cliff and respawn next to your friend (who you only invited over so that you have a walking ammo bin) with a newly refreshed clip of ammo. Or, you could always borrow the marines' guns, they arent that useful anyway.
This mindset simply wont work In ODST. With out regular ammo and vehicle drops, players will quickly shoot away their ammo for their precious AutoMag and be rapidly finding them selfs up a river with out a gun.
For those players who havent already throw their Limited Edition ODST Controlers against the wall, they find themselves in a very hard place, having to chose between the vicious bullet hose SMG, or the highly deadly AutoMag. Myself, Id go with the AutoMag, Maximum stopping power with minimum ammo expense. I mean, You could always toss one in a corner you know you can come back to, but I dont know how well Bungie's constant instance mechanics work, you might find a surprise when you return to retreive your gun.
For those who choose to adapt, they will find themselves becoming very familar with the covenant weapondry. Salvaging these alien weapons will become a new art for some. Finding ammo for your human weapons will turn into an event to celibrate, probably followed by a raging rampage through covenant partols.
Even more important will be vehicles. And Halo 3 vehicles arent exactly durable. With a huge world to explore, that mongoose will become more imporant than that girl friend you thought you had. Protecting it may become your purpose in life. In fact I wouldnt be surprised if Vehicles became a new venue for self pleasure, if you know what I mean. Wink Wink nudge nudge? Dont think I didnt see you lookin at that centerfold scorpion. Ahh yeaa White Boy.
So mabey you ought to go boot Campaign right now, turn a few skulls on, and practice with that plasma pistol. Huh? Yea, thats what I thought.
