I actually think that DSP watches Maximillian streams on the regular and tries to imitate him.
Only that DSP doesn't have the audience and/or the reach to be successful with things that Maximillian does.
If you watch the start of Max's playthrough of Death Stranding one can spot the same kind of "humor" that DSP always tries to do.
Also at the time when the Street Fighter Anniversary Edition came out, DSP copied Max's opinion almost word for word.
He also doesn't have the intelligence or charisma. Maximilian seems to be a genuinely likable person (with the understanding that that's an opinion). Phil is not.
Another big difference is how they respond to negativity. Max will either address it, side-step it, or silence it; most of the time it's "let's not talk about that" but there have been times he's brought out the ban hammer on people. When he's in game and shit isn't working out, there are moments of "WTF, how do I dodge that?!" but he always tries to maintain a mindset of how to get around things. And he is nice, whether it's an act or not is up for debate (because everyone has haters), but he talks nice, he's married with no problem bringing her on stream or playing games with her, and also invites his friends over and have streams with all of them as well. He's not a paranoid shut-in like Phil; his entourage even go to EVO together, as a group. And even if you run into him out in the wild, he's a nice energetic guy... he's also taller than you might think on camera, dude is over 6 feet tall.
Phil on the other hand, wallows in negativity and is so easy to bait into rants. Whether it's in game or real life, nothing is ever his fault. He hides his wife away and the only thing people get is what she likes or what she's cooking. He goes outside of his house once a week; 52 days a year, and sees nothing wrong with it (good clip in the GTG video from this morning), and is scared shitless of any kind of social interaction because of the detractors. The one thing he tries to do that Max does is ham shit up. But it comes off as fake and forced with his knee-slaps and HAHAHAHAHAAHAH or "JASPER DID THAT!! JASPER DID THAT!" Yeah, we got it, calm down.
He's ten to twenty years too late to become a Max Dood. Project 7 shenanigans aside, if Phil stayed focused, dedicated, and maybe try different projects from time to time (and keep up with the fucking trends), he could've been a Max... hell he was on youtube and shit so long ago, it could've gone the way that Max is another Phil. And I'll use Max's Marvel 3 Assist Me as an example. Shit is corny as hell, lots of over-acting and hamming shit up, but it's entertaining enough and Max goes over things that the characters can do in game. It made him endearing and an entry point for a lot of people into the FGC. Yeah, a lot of the older guys see Max as a paid hype machine (which he is), but he's safe enough for people who may not know shit to get interested in it. He also has other videos to get people interested, I personally like his Boss Rage series; I don't need an introduction to most of the games he plays, but I enjoy watching people get the shit stomped out of them and then overcome the hurdle. He's also safe enough to get sponsorships and other shit, aside from doing honest work for companies on the side. I wrote myself into a corner here, but another thing he does is he doesn't show himself off as human. Max will have his dog, his wife, his friends on stream or out in the wild in real life. Phil used to do that, but won't, and the one time an expectation comes up where everyone would fucking demand he go outside (Panda's brother's wedding); he cucks out for Fallout 4 and being scared of detractors, and he couldn't even front her a ride to the airport and the cost of a ticket to get her ass out there for the wedding either. I'm being hyperbolic, but he's not fucking human.
I know I said it before in the above paragraph, but Phil's chance is gone. If there's one thing he is truthful about, it's that no one is willing to touch him. And when lightning does strike... shit... I can't remember the game. The "Worst game I ever played" review; he fucks off for a week to stay in a hotel. He can't even seize opportunities presented to him; while Max, yeah he's safe, and is a paid hype machine, he has no problem taking risks or trying new things.
