Hello everyone, I love Rune Glifberg, and I've had a huge crush on him since I was a kid, and due to this I can't bring myself to even attempt using another character.

So I'm asking, what kind of limitations are there, as I am dependent upon using Rune? I don't really know much about the game tbh, but it's fun as hell and I love Rune!

Skater choice mostly comes down to their special tricks. Rune doesn't have a back or frontflip which are the most easily exploited specials to score lots of points, so comps might be trickier at first. Im unaware how fast his special flip is but it's important that you can land those often. Landing a special trick gives you a small speed boost and flips are the most useable for that. Other than that, THPS1 is welcoming of almost all skater choices, so you do whatever makes you happy.

Do different characters have different ollie heights? If so, does that invalidate skaters who can't wall jump up to necessary places?

The beginning stats of the skaters are all roughly the same, and they're all boosted in the same way through the run so no one is better or worse due to stats. Special tricks are what kind of matter: as guished said a front or backflip helps you gets points easier as they have a base of 4000 which multiplies with spins. I prefer Jamie because in addition to a front flip his special grind is arguably the easiest special input in the game (up up c-up), and you use special grinds in the run a lot for a slight boost in speed.
