DProject: Yeah, I believe so. I don't think it matters whether it's FAT32 or NTFS, or what model it is. But when it comes to capacity, you can never have too much of it. I'd recommend AT LEAST a 200 gigabyte hard drive. As I said, in my case 40 minutes of uncompressed gameplay video footage takes 90 gigabytes of space. Uncompressed 40 minutes of audio (WAV format) is about 1 gigabyte. But then you need to realize, that Windows, all the installed programs, etc. take space too. And I like to keep all the raw footage as long as possible, in case any errors suddenly come to my attention and I need to re-edit something.
Detlik: So just 200 GBs is enough?
Also everyone which game would you like to see beside Inquisitor? I have some cash to spare and I would want for you to be happy...you know to bring some small fanbase to start
I think 200 gigabytes is the minimum, if at all possible you should get more. Unless you're using the 200 gigabytes solely for video game footage and don't have to worry about other stuff taking space, such as Windows. Then 200 GB should be sufficient, if you steadily remove older raw footage you no longer need (which in turn means you'll need to compress your footage into full, completed gameplay videos often before you can record more raw footage).
As for the other question, I once again recommend you start off by making a Let's Play of a game you're familiar with already, or a game you're otherwise really eager to make a Let's Play of. As it is your first LP and you still need to learn the ropes when it comes to entertaining commenting, it's much easier to start off with a game you really want to LP YOURSELF. If you decide to do a LP of a game that later reveals to be a big bore for you, the audience will know. You will most likely come off as bored, and making the LPs will become a chore. You're not enjoying it, and the audience will neither. You remove that risk by LPing a game you've played before and love. I really recommend that you start off like that, because then you don't need to focus on the game itself that much: instead you can practice on how to be entertaining. After you've gotten some experience about making commentaries, you can move on to recommended / suggested games if you feel like it. But even then (like I said) you shouldn't do Let's Plays just to get fans. You should do them because you enjoy the game and want to show appreciation by making a Let's Play of it. If you get fans that way, then everything went better than expected. But you should never, ever think that a fanbase is a given: you won't necessarily gain followers just by LPing a game someone wanted you to LP. Think it like this: Say there's a new TV show coming, that has a really interesting setting: there will be FREAKING RAPTORS RIDING ATOP HOVERBOARDS, BATTLING AN ANCIENT EVIL CLAN OF UNIBROWED SAMURAIS. But when the pilot episode airs, you suddenly realize it's total crap. What I'm saying is: even if you plan to make an LP of a game that's really beloved by many - if the LP itself is not entertaining, the people won't watch it. Plain and simple! That's why you need to get experience, hone your commenting skills, and stuff like that. Remember - the most famous guys on the internet, who do Let's Plays, worked HARD to get tons of subscribers. They didn't just upload a stage of Mario Bros., and the next day have thousand of people praising the video. Rome wasn't built in a day. I'm just saying this so that you don't get your hopes up and immediately expect to gain tons of fans, even if it never happens. If you're GOOD at making Let's Plays, it is possible though!
Again, I wish you the best of luck on your LP career! I'm still excited to see what kind of material you manage to produce.
