That's a pretty good clock. I wouldn't know what kind of features would make a truly excellent alarm clock but tracking how ones feels when they wake up is pretty cool.
I've played through Going Down twice and neither time did I play it vanilla. I think the first time I played it I used Weapons of Saturn which is just slightly more powerful compared to vanilla. It's really hard either way, but it's so good. I can't imagine how grueling it is with vanilla weapons.
I think, level for level, Doom 64 has the best campaign out of all the official Doom games. It arcs up real good, the level designs have way more hits than misses, and the atmosphere is the best the series has! Retribution is probably the best way to experience it.
Also playing wads like Valiant and Going Down is an important part of the "Doom experience" if you ask me. That's what Doom's become for me anyway.
