Personally, I would have to say no thanks. The one thing about Halo that was so fun was the blend of realism and massive, crazy insanity.
For example, people want things such as knife’s as weapons. This just does not fit into the Halo way of playing. It is way more fun and unique to beat down enemies with your super-human strength then to stab with a knife. What, can a Spartan not kill with his hands? Have you even HEARD of Halo?
Plus, people want things like a flashlight as a weapon…? Why? You don’t need a glowing stick of light to kill an enemy, when you are a super soldier. Read the above paragraph. Spartans have lights in their helmets, and do NOT need a flashlight, thanks you very much.
Now, the unrealitic things, that make Halo what it is. Example one, of course, the HALO ARRAY.
Yes, because you can make a world on the inside of a giant metal ring, with a sun floating in the middle. And yes, even though the shape of the thing is a ring, it has a gravitational pull down, when technically, people should be sucked into the giant sun. Think of it like the earths gravitational field inside out and Halo shaped. You would just float away… But this is what makes Halo so amazing. Who cares about reality!? It’s the enemy of creation and imagination! What would be better? A ring world or a metal glowing planet? Halos all the way!
Also, the SPARTANS… seven foot tall MJOLNIR-wearing, skull-crushing, alien-killing, green-colored super soldiers. This, again, is NOT realistic, but it is cool. And, in video games, cool outweighs reality any day. And if you thought super-soldiers in 2552 was unrealistic, try Captain America! He was created in the 40’s!!!
Last, but not least, aliens. Ah yes, the little waddling creatures waving their stumpy arms over their heads and screaming because their horse-leg cousin-to-the-Predator Sarge was exterminated by wee little marine who is using the BB gun Magnum from Halo 3. yes, the grunts ARE the foundation of Halo. No grunts, no Halo. Simple. Now, in Halo 1-3 you hear various things from these little monkey-aliens such as ‘The Demon’s dead. Dibs on his boots!’ Or ‘He was my best BUDDY!’ But now, in Reach, Bungie listened to the people who did not like Halo but came along anyway and demanded change, saying that the game was too ‘unrealistic’. So now, Halo’s foundation, the grunts, no longer say their catch-phrase outbursts of insanity and now say ‘WHA CHA CHA CHA!!!’ Why!? Why ruin the BEST thing about Halo? Also, I preferred the elites saying 'You shall die by hand! to ‘WARB! WARB! WAAAARRRRRB!!!’ when they run at you with a sword. (Also an unrealistic weapon, but cool, right!?)
So, in my opinion, please let Halo be the fun, crazy, awe-inspiring and UNREALISTIC game out there. And forever keep it that way!
