Your favorite game mod?

Because bloodlines gets even better with mods. Not only does it fix bugs (even if you did not experience any major ones, you did run the risk of it), but it also restores cut content, that they never had time to implement due to the game being forced to released at the same time as HL2, thus you get more content (as designed by the developers and then re-implemented into the game with the pieces needed to make it work added by the modders). VtM: Bloodlines with mods is an objectively better experience, thus I don't see any reason not to mod it. It's not like it's a hard thing to do either.

Quite a few games are like hamburgers, with certain mods topping it with cheese or whatever you put in your hamburger that makes it more attractive it for you. Answers like I don't like hamburgers or "sick fuck, who would want an attractive hamburger you're weird mate are forbidden :P certain mods are really, really improve on a game. Skyrim is an okay-bad-brilliant game, no matter how you see it - but for example SkyUI fixes it's UI, making it much better, regardless of one's stance on the base game.
Torchlight 2 has tons of mods, from infinite money to invincibility potion to weird effects, characters (and very likely nude ones :D ) and even ones that makes the game harder - everyone can have their favourite mod. For example I like to laugh at silly, non-lore mods but I would hate to play with them.

So, if the game has so many problems, the creators should fix them

Totally true, but strawman arguement. Noone mentioned reason of buying game, or even it's creators. I'm again monetization of mods because Bethesda will be even more of a slacker and just wait for modders. And cash in on them. But there is nothing bad that one buys a game because it will be better / tolerable with mods, because if a consumer likes it, it's okay. One buys games to have fun, and if mods required for them but doable, it's great. But really, in a lot of groups Skyrim and such's quality usually mentioned as "great with mods". More attentive people usually makes a difference between great game to begin with, and the ones you need to make good.
I know you like to get into not even serious arguements :P if you still want to stick to your no-mod arguement, by simply phrasing it as you want to experience the game without fixes, or changes made by others, so you have a clearer picture, it's perfectly valid and won't random people bash at you. (But again, knowing you you don't give a darn, just send some microbes after then and wait :P )
Really sorry if this seems to be pretentious or anything. I'm totally up for opinions if they can be explained (like you did to Fnord) but I still try to change them a tiny bit to help avoid future arguements with anyone. I'd just like to think I can prevent a few random internet arguements, making other's day better :)
