Don't laugh at your own jokes
Especially if youre solo casting

do what i did and do practice casts until you don't blow, i still blow tho so take my advice with a grain of salt

I'd say don't try starting casting unless you at least somewhat understand the game. With your experience I don't think you'll even know whats going on.

And don't call every play insane like Bren used to do when he was starting out...

Thanks Bren, I can easily copy and paste my advice I gave you from a year ago now

every play is insane tho, you just haven't experienced tf2 like i have https://i.giphy.com/d3mlE7uhX8KFgEmY.gif

In general anyone with a decent understanding on the game can do an alright play by play cast but imo in order to do color commentary/analysis you should probably have a good bit of experience otherwise you're just talking out of your ass

Be like the OG casters and mumble cast pugs. Its funny as fuck, makes you adapt to random shit on the fly and can be loads of fun for the people that didnt get picked for that pug.

Try not to stutter, but if you do, roll over it like you did not in the first place.

practice by casting minecraft trade servers

Download STVs of matches from any season of ESEA still available and just kinda talk through them. Sitting in a mumble watching PUGs is also an option. Just get the practice in, the gamesense and such will come with time.

i mean they let me cast just cast over some game play from ESEA and send it to a producer for TFTV.

This is what I do to practice, would recommend.

Slin has a good video I usually send people when I see this question get asked: https://www.youtube.com/watch?v=8DVHcKTg5r0

What I did, and what Slin recommends in his video, is to just start doing low level casts and put them in a place where maybe not a lot of people are going to watch them, but still somewhere you can show people to get feedback. For instance I solo casted 3 or 4 seasons of Open and UGC on my own personal channel, where I didn't get many views, but I would send the casts to the teams that were playing, and they would be able to give me feedback. One thing I learned doing this is that low level teams LOVE to be casted, and generally won't be too harsh if you're still new at casting.

Also just to talk about #4's point on needing experience, lots of good play by play casters (in TF2 and otherwise) aren't actually very good at the game at all. When I started casting I had literally 0 comp experience, it took a lot of time and effort to learn the game, but I do believe you can get up to the knowledge level required without playing if you're looking to do play by play. For colour casting however you will for sure need some decent experience, if you don't fully understand what's going on as a colour caster you're going to mess things up and people are going to catch you on it.
