Having to put the "s" for example on the end of "deathclaw" in order for it to register is just plain stupid.
#3: 'Deathclaw' is not accepted.
#7: 'Addicts' not 'atticts'.
#9 & #11: It's awkward figuring out what it's trying to say here with 'below' and 'above', especially with capitalization. 'the below answer' and 'the above answer' might make it more obvious.
#12: 'Hsu' should be accepted, especially considering it's already stated that he's a colonel.
#19: 'Laser', not 'lasor'.
#20: If you're going to make it specify further than 'power armor', at least consider accepting 'T51', 'T-51', and 'T51b'.
#25: 'Zion' should be accepted.
#34: 'Caesar', not 'Ceaser'.
#40: 'RobCo', not 'RoboCo'.
