Heh. Maybe it is because I came to SR from Hero System and D&D, where you have REAL bookkeeping to keep track of (especially Hero System), but changing initiatives like that is not exactly time consuming to me. Especially when you're used to dealing with three defenses (physical, energy, mental) that have two types (normal and resistant), two HP gauges (BODY & STUN), MP (END), recovery rates, Combat and non-combat move speeds, OCV and DCV that change based on CSLs and maneuvers, trying to roll low when acting and high for damage... And that's just for one character.
Seriously, even after they added more complexity in this edition, SR is still one of the simpler systems out there.
