lucky day for you mbezruki! I'm currently making a Halo mod for SoaSE.
Check it out here:
Halo Mod

Well, if you wanted to get carried away with it, you could probably find parallels between the Sins storyline and many other futuristic "Man vs Universe" Sci-Fi epics. It's nothing new, nor is it a convention restricted to SoaSE or HALO.

Besides, HALO is overrated garbage that I'd rather forget about. Never in my life have I seen such a thoroughly average shooter attract so much attention. It's not bad, I guess, but it is remarkably undeserving of the praise it gets, and there's a lot out there that is superior to HALO by leaps and bounds. this review fairly well echoes my sentiments about the HALO series.

(Sorry I got a bit carried away with the HALO hate but it's a huge pet peeve of mine )

Someone please put me out of my misery...

and thats why i'll never play xbox live

while i do like halo it doesnt deserve the rep it has honestly its just another fps clone

as for sins being comparable you can say that for almost every game out there and its not really anyones fault its just that pretty much everything has been done and all thats left to do is make clones, sure the games are all a bit different but when it comes right down to it they are all built on a basic idea that has already been done many times

Then might i suggest Universe At War:Earth Assault, as that is the Exact premise, humanity isn't even a proper faction, its just something there to get blown up in a variety of interesting ways.

Sins is soooo hard to play!!   I am getting my butt handed to me every time I play.    I need alot more practice I guess. Halo... meh... just another shooter.
