To Wait, or Not to Wait?

[ToxicSlurpee]

So, SE:V is in the works, and I'm working on an SE:IV mod (that, admittedly, is more complex than I intended and is nowhere near done). So, I find myself wondering...should I wait to snag SE:V first, or should I press on and attempt to finish it as quickly as humanly possible?

I'm leaning toward the wait option, but still working through it anyway. There will probably be at lesat some similarities, of course, and SE:IV has some limitations and some quirks that bother me.

But, really...what do you kids think?
