Of course Garriott has gone nutty for a long long time now, but man - it's like a once great rock band, you've got to respect the back catalogue. The Rolling Stones have been a shit band for 3 times as long as the time they spent making good music, same for Paul McCartney. Fuck, it's hard to even think of a rock band that stayed great for more than a decade.
Hell, U2 were always kind of dull for me, but if you were into that sort of stuff then they probably had the longest period between first and last 'great hits': Sunday Bloody Sunday in 82, to The Fly (off Achtung Baby) in 92 - 10 years, and they've been shit for at least 20 since then.
Authors? How many 'great authors' (not just popular hacks, nor just capital 'L' literature, but anyone whose books are loved for the writing rather than their franchise or the equiv of Bioware fanboys) make it past 5 good books? Ok, theatre writers tend to dwarf that, but that's because the theatrical tradition allows (even encourages) writers to explore the exact same plots and themes over and over again (e.g. Shakespeare in Julius Caesar, to the War of the Roses series, to King Lear - could reduce all of his plays to about 10 themes/stories, and that's the all-time-great). Conrad wrote the same brilliant story over and over again. Twain was possibly the most gifted novelist, but he spent most of his life writing whatever he could to pay the rent. Gibson did Neuromancer and a couple more then cruised for the rest of his career. King is, well, the King of pulp - the Beatles of book-writing (as opposed to the Mozarts and Wagners of the capital 'L' literature set, and as opposed to the Led Zeppelin and Pixies of better authors with lesser coverage), but the length of his career (which frankly went to shit decades ago, aside from the Dark Tower series, and that only retains its quality by virtue of him having the luxury of working on one every 5-10 years or so, writing his usual milllionaire pulp while waiting for inspiration).
In that context, should it be surprising that most great game developers don't make more than a couple of true greats - hell, by the context of other 'creative commercial' industries we should be expecting no more than 10 years out of the very greatest. In that context,
Willy Loman Richard Garriot might not be a great developer anymore, but respect must be paid.
Also, for all that he talks about story, the Ultima games weren't Larping in the TES sense. It was about giving players the mechanics to have their actions reflected in game. Story-whoring perhaps, but even then it's more of the 'interactive setting' than a linear story in the modern Bioware sense. It's what Todd has never understood - the guy is very clearly wanting to remake Ultima 7, over and over again with newish tech (the guy is at his best in interviews when he talks about why he thinks U7 is still the best game ever made, not for it's time, but still the best of all time - he sounds like a downright Codexer in those moments) - but he has never got his head around that freedom without the world recognising your actions is just a souped up notepad. Take out factional clashes, consequences for dumb actions and the ability to 'break' the developer's desired plotline for a region, and you may as well just have your game on wheels. I never felt like that with the Ultima games.
And whilst MMORPGS aren't my thing, Ultima Online is arguably the best one that the western world has made. At least you can see some genuine ambition there - sure it's Larpy, but it was an attempt at true world creation, not a theme-park, not a grinding/raiding game, but a true attempt at creating a world where folks could be a farmer and crafter, just like they can be a warrior or a bandit. Sure, it didn't work out and eventually it became a working model of why Hobbes was right about anarchism being the worst of all possible states, where you'd get mugged for your boots on your way to the bank
. But I can appreciate it as a game with ambition, rather than yet another cynical WoW clone.
So I'd probably put his decline after UO, with U9 being a managerially fucked up exception, and U8 again being a failure but one with a real sense of ambition underlying it (e.g. the spell system, but also means of interacting with the world that would later be put to much better use in Gothic 2).
