Has come up before.
Tiy is generally opposed to this on the grounds of having some consistent and predictable game elements, and I tend to agree w/ him.

Well its not like you have extra damage from the start in default, and also i doubt that a slightly larger blast radius would make such a world of difference. Furthermore, if you get it in a crate, wouldn't it be nice to have another trick up your sleeve?

Thanks anyway for the quick reply.

Maybe "Extra Explosion" utility and customizable radius would be good?

I would think it makes the most sense for the weapons to have consistent methods of attack, and radii. I mean, take something like the cluster bomb. If you're already making it stronger, why should it also have a larger radius, and have each bomb have a larger radius? You're supposed to make the damage itself stronger if you hit, not *also* make the hitting easier, or even different. That seems like it'd be a different power-up altogether, if at all.

Some game option to have higher radii, or to make the radii larger upon using that power-up might be an alternative, but I can't see it being a priority.

Anyhow, if it doesn't matter much, why bother? I think this would upset way more people than it'd please, because a lot of the game is about calculation- it seems strange to mess with it with no real logic behind it. It could be fun as a mayhem mode or something, but not as a primary mechanic- I think the changes would just frustrate me.
