Have been considering with trying this mod out, but...

[ARWINGx1]

There was 2 main reasons for why I wanted to try this: my Pessimism tends to "scare" me away from games that're focused on PvP, but on RP focused games (or in this case, Mod) like these, PvP skill/experience are less relevant, right? (especially Competitive PvP, which are probably about nonexistent, I suppose?)

The answer to this is not entirely straight forward - yes and no. In the sense of seasons and rankings and so on, you definitely won't find 'competitive pvp', but pvpers are a big part of the community here, and definitely get pretty competitive! That being said, this is a sandbox - if you do not wish to partake in PVP, it need rarely come up. That is not to say you can or should necessarily completely avoid it - but for the purposes of Roleplay it need not feature often if you don't want it to.

Also, like most PvE focused games, I do eventually reach a point where I feel "burnt out on content", but for RP/PvP focused games, the "unpredictability" with the other players keeps the game from getting dull, or at least stalls it.

True, basically. Though this really isn't that much of a PVE oriented game - you certainly can and will pve, but the endgame is 'player interaction'.

BUT! I have been hesitating, primarily because of two "issues", (which is on my end) which is that, at least when I'm still a "beginner", I feel like I may not be able to roleplay consistently enough.

Also, I'm not THAT familiar with "active" roleplaying, and aren't sure if I should do it with fictional ones, or if "fictionalizing myself" is (at least) not uncommon.

Theres only really one way not to be a beginner anymore - be a player. What I am trying to say is: don't be afraid of being a newb, everyone has to be at some point. Just get stuck in and enjoy yourself - you'll learn as you go, and find a grove comfortable for you. As to creating characters, well there's a huge number of ways to go about it - there are even a few good guides in tutorial section (in general that section is worth your time, definitely). A good piece of advice for all roleplay characters, when you lack experience - take one or two character traits you possess, and amplify good and bad. Its easier to play a hyped up version of yourself than it is to play an out there concept. In time it becomes easy, and you can compartmentalise.

This 3rd one might be minor though, "on average", I'm guessing that it's enough when I'd be able to ramain online, without feeling "exhausted" between 30 mins ~ 1 Hour? (straight)

Not necessarily an issue - this is a sandbox game, after all. That being said, there are activities you will find impossible in that timeframe - events can last longer, and there are activities (like sieges!) that can go longer still. However, its entirely possible to just play for smaller chunks.

I assume that with transport/capital ships, "Piloting Skill" are less relevant than Aim?

As with any skillset, competency in one can make up for deficiencies in the other, but learning to turret steer is pretty vital for capital ships.

Also, I feel like I have the potential to be a efficient businessman... or a Manager of some sort. ('course, there's alot of info that I'd need to catch up on first)

As for Factions (& Whatnot): have a hard time deciding between Interspace Commerce and Orbital Spa & Cruise, and would appreciate some more insight, to help me decide which one I'd be suited for. IF there are any that'd be better suited to me, compared to the 2 I mentioned.

I'm biased of course, but err... business man, ey? Come join Republican and Daumann If those two you mentioned are your choices, it might depend on what you want to do - but of course you absolutely can do both. You're free to have as many characters as you wish. Interspace is, I believe, the more active of the two - but I did see someone posting about restarting an OSC faction, so you may wish to consider that.

Overall my advice is: give it a try, and see for yourself what you think. Make indie characters, fly around, explore, join all the discords and see what you enjoy and what you'd like to do in the future.

That last one was just a figure of speech. Sorry 'bout the misunderstanding.
