Hi! Sorry for the slow response..
I like what you did with the changes. Less power means it is less of a super efficient plasma replacement. I will be looking at the selling costs soon.
A few things I noticed (and somehow failed to mention before..?):
- When referencing the new sprites, you have some as *.Gif, instead of *.gif. On Windows it doesn't matter, but for a Linux user like me, it makes the mod crash.
- The mod changes the name of regular laser weapons, but misses the heavy laser, since that one is "STR_HEAVY_LASER", not "STR_LASER_HEAVY_RIFLE".
- The ufopaedia article for "Further Elerium-115 research" doesn't require anything, so you can see it at anytime. Also, maybe it would fit better in the "Alien Artefacts" section, right below Elerium-115, than in the weapons section?
Another, not really necessary to change thing:
I use a mod which flips the laser research tree (start by discovering the tank, then heavy laser (optional craft weapon too), then rifle, then pistol (optional sniper rifle and scatter laser). This makes the naming convention pretty awkward, especially with the renaming.
I simply removed the renaming line from your ruleset and changed the new weapons to "Elerium Laser X". I was wondering if you might consider a more "neutral" name series? It would also make it more compatible with optional laser weapons.
Nice work on the multiple lines for the ufopaedia, btw. I didn't know you could do that!
