There's a handful of very well-executed quests. It's somewhat like a very high density version of the light world in aLttP. I believe the present level of high density sacrifices immersion more than it should, but that's just my opinion. It is very much a walled garden compared to the patchwork of what was developed, redeveloped, and re-redeveloped by many different people with many different ideas that was old GtA. Maybe that could come off as fisherprice-esque? The lack of that patchworking very much hurts in regard nostalgia. Unfortunately, I don't have a pair of fresh eyes to say whether the walled garden is better from a neutral point of view.

The present gameplay value could multiply if you could replay quests on the same account for stats (completions at 100%/Any%, fastest times at 100%/Any%, etc). Otherwise, the only other single-player things to do are archery, gralat hunting (limited), and some trading card hunting (also limited). Events could potentially be improved at this point if any player could host certain events structured enough to not require administrative priveleges, but whether that would have any ROI is questionable.

Usually when I decide to log on, there aren't many players aside from idlers. If a solid player base ever happens, there's the custom guild system/MoD fort (haven't seen), the card game, pking, sparring, and events. Meanwhile, in regard to sparring/PKing, I'm not sold on clientside HD at the iClassic scale aspirations (considering iClassic), but I imagine it would still be fine at 2001/2002 GtA scale.
