Since you're asking a question like that, I will go on a stretch and assume you're not really into programming (or you're just a very lazy at googling, in which case: Go and google it!) Therefore, my answer will be: VERY. They are ... Kind of similar and syntax that works in C will, for the most part, work in C#, but that's about it, really.

Well, as far as Googling goes, I thought I'd ask since this thread seemed like an appropriate place. As far as programming, I've worked with Corona SDK (Lua) and Visual Basic, but I want to learn C# (or C++, but apparently C# is better now?).

Watch every Extra Credits show made this weekend, it should take you a day or day and a half depending how much you go back to take notes.

There's few free resources that can give you better insight into good game design or why some mechanics work and some don't than Extra Credits.
If you have the time you can just subscribe to Safari Books for a month or two, the library is extensive.

Wow, I somehow never knew that sight existed. If I ever actually get a job, i'll definitely keep that in mind.

And yeah, Extra Credits is definitely a great bet for insight into games.

They don't support Kindle officially, but I've been able to make it work so far in a Kindle browser. They definitely rock, and allow note taking and such.

Take it from someone who's recycled 1000s of USD in tech books, owning tech books is for suckers:)

I dont know "C#". I started this semester studying "C". Only other language I know is Java.

C# is actually very similar to Java. There are some major differences, sure, but if you can work with Java, you will get into C# quite comfortably.

Where/when will these go online?
EDIT:
....OH, that's what you meant. Silly me xD

Make sure you have basic design docs before you try to enlist the help of others or at least a skeleton plan to work from, it can be quite intimidating starting working for somebody, even on a voluntary basis, and not have some sense of what the scope of the game is going to be.

If it's a volunteer sort of thing you'll likely have to negotiate details and change things a bit if the other folks don't share the same vision.

But, the sooner you define what is and isn't in the game, the easier you're going to have it. I think defining what isn't in the game is sometimes more important than what is in the game.Most games that fail to ship on time do so because of feature creep.

Although often a defined scope which is way too ambitious for the resources available also causes that.

EDIT: Speaking of which, I need to get back to work on my comic. I only have 6 weeks left before launch. And 3 before that 24 hour comicbook thing.

Outside the realm of PC gaming, you could always try your hand at making a game app. GameSalad is a mostly wysiwyg tool for making games. I've tinkered with it, but that's about it.

I don't remember exactly why, but I recall reading in several places the Gamesalad isn't very good. Corona SDK is a nice alternative for mobile development, though.
