Lollipop Chainsaw was excellent. James Gunn wrote it and if you've enjoyed any of his movies, you'll love the game. It's short, only about 6 hours, but that's actually the perfect length. Definitely does not overstay its welcome and never gets a chance to start feeling stale.
I never got around to Killer is Dead either. I'm not sure I know anyone who played it as a matter of fact. It got butchered in the reviews though. It also came out very late in the PS360 generation, and I think at that point people were just catching up on good games they missed rather than spend time on something that got trashed.
Lost Odyssey is great. Truly great.
99 nights and the sequel are only for hardcore musou fans.
Dunno about the rest. I played a couple lost planet games but they were so forgettable I forgot about them when I turned the 360 off.
Never played Killer is Dead but did play Lollipop Chainsaw and really enjoyed it. Always kind of think about replaying it again from time to time.
