Thanks for the tips, soup_alex! Unfortunately, making a pop shield will be difficult for the mic I have because I don't even have a stand, so I've been clipping it to the collar of my shirt. When I upgrade to a new mic though, I'll keep your advice in mind - sounds like a pop shield should be pretty easy to make.
And yeah, it is a mini TRS, and it is old, so it is very likely that the connectors aren't what they used to be. I'll switch to a slightly newer mic for the next few videos.
Also, if anybody has any ideas for other obscure games that deserve an LP, let me know - I'm searching for opportunities.
NP. Call me a microphone nerd :|
And you might find that with most mics larger than an lavalier/electret (I imagine that the mic you're using falls into this category), the inbuilt "counter-pop measures" (i.e. a bit of foam over the diaphragm) is already sufficient to cancel all but the most dramatic plosives. But it's not a big deal.
Also, if you're a cheapskate (like me!) you could just make a mono recording/mix of your narration, which would do away with the unusual stereo behaviour.
...it sounds like you might be getting tired of Star Zoo! (and I can understand why)
If you're accepting requests, I have a few in mind:
I'm personally a big fan of WWI Medic, which although does belong to the Bay12 family, is not a curses-based game (as are LCS and Star Zoo)
Alternatively, try Corin's... which
is curses-based, and more importantly I haven't got a fecking clue how to play, so an LP could really help me get a lot more out of it

Or, there's always LCS? Admittedly, Grimith is already engaged in an LP for this title (and highly entertaining it is, too), but it really lends itself to an ongoing "diary" sort of LP, and it's so open-ended every man and his Canine Hero could have their own series and they'd still all be different.
