Mega-Mods...
Good: Many different mods working together, tested to insure a minimum of conflicts.
Bad: One person's idea of what should be there. Just read the SH3 forums to see how it works (or doesn't). First you have Super-Mod of choice, then you have dozens of other mods added on, with the same conflict problems. Then you get complaints: "I'm using your supermod, how come my game crashes?" Then you get "I wish somebody would combine the best of these two (or five) supermods." Then you get modders asking "Whose best? Yours? Mine? Our ideas of what's best aren't necessarily the same. You want Mod A's graphics, Mod B's AI and Mod C's sensors, while I think Mod A's AI is better and Mod D has the best graphics."
I'm not knocking Mega-Mods - just the opposite. I love 'em. On the other hand if I could have all the combinations I wanted to try I'd need another terrabyte drive just for Silent Hunter.
