Hello my name is Metaladdict.

My take on Mass Effect crossovers:

At the time of writing this (6-9-2015) there are about 2.2k crossovers stories. I love the concept of crossovers with the Mass Effect universe. Its has a lot of potential especially with universes like the X-COM universe. One of the things that seemingly is ignore in a lot of first contact fictions (not crossovers alone) is common sense. The thing that motivated me to write this is one of those situations. When the Turians encountered a human ship the FIRST thought is their heads is "HEY we can conquer these guys!". Turians are not evil mustache twirling monsters. They are people, people with different value's, but people none the less. The most stupid version of this is where a lonely admiral decides to declare war on a entire race.

X-Com

There's a lot of potential there. A people that pretty much have been trained to hate and kill aliens facing a people that at the end of the day just want to preserver the status quo of their people with as little losses as possible.

But unfortunately is almost always end with either the humans destroying the council or the humans being holier than thou in the peace department.

The best version in my eyes is where the council and humanity is in a sort of cold war state, where they are trying to figure out what the other is trying to do. The council in this situation is trying to convince the alien weary humans that their actually good guys so that they join them. Or alternatively try to force humanity to join the council by other sources of political pressure. Of course the council will want to try

Star wars:

I don't think this works, for the simple reason the republic or empire being to big for the council to actually matter in the grand scheme of things.

Halo:

Actually has a chance of being good, but usually end with rofl stomping.

Fallout:

Can actually really work. The Fallout universe has a chance of fighting back against the council, but not to the point the they can easily defeat anything that the council throws at them. People forget that humanity has lost A LOT of it's population, meaning their military should absolutely tiny in comparison with a galactic society they are facing. Other fictions plainly ignore this as well, but it's extra painful in the Fallout universe where the majority of the population was eradicated.

Other:

Anything that involves magic, instead of technology is a no go as far as i am concerned.
