Crazy comment lol as ther 3 different type of games plus every game has some flaws - and hav you finished both doom and animal crossing I doubt it
Considering one cannot "finish" Animal Crossing, as it's a life simulator with no 'final boss' to defeat and credits to see (unless you count K. K. Slider), I am reasonably certain
no-one has
ever "finished" a single Animal Crossing game. Ergo, moot point there.
As for DOOM Eternal, no. So? I don't need to have "finished" a game to know if it's worthy of purchase.
If you think I do actually have to do that, then I dare you to finish Assassin's Creed Odyssey. Or Ratchet & Clank PS4. Or Batman: Arkham Origins. Or Layton's Mystery Journey. Or Mario & Luigi: Paper Jam. Or Paper Mario: The Thousand-Year Door.
Basically, one can be justified in making a decision about a game's quality and purchase-worthiness without having finished the game in question. And if they give up partway through due to tedium or frustration or just losing interest, then that's a valid decision; a valid opinion.
