It would be kind of like Golf, where you draw back the bow, but if you hold it too long it gets wobbly and throws-off your aim. You're going for the Zen horseback archery style of inhale & draw, then exhale and release in one fluid motion. And of course, you're playing in all kinds of exotic settings and times, even like Crouching Tiger Hidden Dragon. If you go side-saddle, you'd have to gain proficiency in both left- and right-handed shooting. You could have a jousting game of sorts: just run around and shoot your opponent. Neck would kill. Everything else would bounce off the armor. You win prizes, gold, artifacts (that help you on your quest), and ultimately the slay a dragon, or free some people or find a soul mate.
