I'd like to section it off a bit.

Non server based: Servers are only required for authentication if at all, the game is actually hosted by one of the players if multiplayer.
Microtransactions: No
Lootboxes: No
DLC: Sure, provided it's not cut content from the game like on disc DLC. I don't have a good hard rule here, but the sooner it comes out, the more it looks like cut content.

Server based: A multiplayer game that requires servers for more than authentication, like MMOs.
Microtransactions: You're getting real shady here, any currency to be bought must also be obtainable in game. Balance is key.
Lootboxes: Cosmetic is shady. Hopefully your players reward you by not buying it at all.
DLC: Sure, provided it's not cut content from the game like on disc DLC. I don't have a good hard rule here, but the sooner it comes out, the more it yada yada blah blah.

Server based with subscription: Ditto, but with a monthly fee
Microtransactions: No
Lootboxes: No
DLC: Big expansion pack DLC only.

Free to play:
Pay to win is a shitty move to make later after people have already bought in because they liked the previous non p2w model. Otherwise, feel free to do whatever, I just very likely won't play p2w.

For this I would probably classify microtransactions as buying an in game currency or quality of life upgrades(bag space), and something like a character as a cheap small DLC. This is of course a general guideline, and something like a character could still be completely OP to try pushing for money in which case I'd consider it p2w. In general, DLC is OK, and while I won't circle the wagons about p2w stuff in completely free games, I probably won't even give them a shot. Phew! This was harder to pin down than I thought, and it's likely not quite right yet. Multiple revisions already. =P
