5 mods that people need to stop making
The 'Horror' Mod
Dark hallways, small quantities of weapons and ammo, cheap scare tactics. There are so many so called "horror" mods already out there and very few of them actually manage to pull it off. Far too many people are using darkness as a scare tactic, whereas for the most part, it is just annoying and disorienting.
The Zombie Mod
They Hunger did it well. They Hunger 2 and 3 got old fast. Every other zombie mod since then has been dire. Zombies are all well and good but there is little variety in the combat throughout. Slow shambling enemies make for slow shambling mods.
The engine upgrade / downgrade mod
Black Mesa looked incredible back in the day but now the level design is starting to show its age before the mod has even been released. Then there are the ones that go for the opposite approach. Take a new game and remake in for the old engine. The word 'downgrade' is rarely a good thing and more often than not implies that the 'latest' version is not stable enough to work with. HL2 works fine on it's current 7 year old. HL2 would not work fine on an engine that is 7 years older than that.
The Halo cross over mod
Nobody wants to play Halo in the Half-Life engine. Nobody wants to play Halo in the C&C Generals engine. Nobody wants to play Halo in the Homeworld engine. Nobody wants to play Halo on the GTA:San Andreas engine. This doesn't just apply to Halo, but it's certainly the most common culprit.
The "realism" mod
Mods that claim to bring realism to a game never EVER do. Real world weapons? That's a model pack. Better textures? That's a texture pack. Updated sounds? I... I have no idea what the hell that is, but it is not a mod. A true realism mod would make bullet impacts inflict more damage, resulting in instant death or bleed-outs. Health kits would be removed and instead, wounds would need to be tended to by a doctor / surgeon. Fall damage would result in broken / sprained limbs, reducing speed and inflicting pain damage the more you move around. All of this would make most games impossible. HL1 for example, Freeman would not be able to enter the test chamber because his suit is lacking a helmet. If he did, as soon as the experiment starts, he would drop dead of radiation poisoning.
There are probably more, but these are the main culprits...
Don't FUCKING post then.
