Judging by your description of Gundam, you've only seen Wing, later parts of Seed/Destiny, and the like. You might want to try Gundam Unicorn, or UC stuff in general. Three grunts in inferior MS nearly kill a skilled pilot with a clearly superior MS in Unicorn's first couple minutes.
As far as 2009-2010 horror, have you seen
Umineko no Naku Koro ni ?
