Quarian- Maybe, They are really cool and have Tali, Kal'Reegar, and Teyrn Loghain...I mean.
Turian- Garrus, that is all you need to know.
Batarian- I'm gonna be honest, who the fuck cares.
Asari- They're so squishy, where are you supposed to get a decent grip?
Salarian- Live 40 years and be in Gilbert and Sulliven. Wait but be a target to Krogan sexual deviants. No thank you.
Elcor- Uncontrollable Excitement: You have not experienced life until you have spoken like an Elcor.
Hanar- This one thinks you should help spread the word of the Enkindlers. Scratch that, it's just a big stupid Jellyfish.
Volus- Strong economy, Zero Military. However, being a Biotic god is tempting.
Vorcha- Can't speak properly, die really fast, routinely get set on fire by me. No thank you.
Drell- Having a photographic memory is awesome, until you remember walking in on your parents doing it...
Geth- OMG that would be cool, but the Geth end solution seems kinda...meh to me.
Krogan- Wrex, Grunt, the Shaman, and Headbutts. Oh and don't let me forget the quad. I think I'm in love.
