The VT05 also has a unique feature missing from subsequent terminals in the series: monochrome NTSC video input, allowing relatively straightforward use as a secondary graphical display on a modern system.
We spent hours playing VTTrek during college on the DEC-2060. Glorious battles between the Federation and Klingons. I only wish I had video of some of these games. The game was written in MACRO-10 and featured 3D game play using ASCII renditions of stars, planets, and ships. The Enter key on the numeric keypad certainly took a beating as that was your propulsion key (if I recall correctly). There's a former DEC employee who posted the source code and more information on the game http://raspuzzi.org/vttrek/vttrek.html
Edit: special thanks to MRC for being so kind to me at Stanford in 1980/81. I asked dumb questions and he sent me in the right direction.
I love DEC VTs. Spent the first few years of my career as as a VAX sysadmin, and basically lived in front of various VT220s, 320s and 420s. Never got to use an original VT10x though.
I still hanker for a VT420 as they were the best - I can't afford one though[1], so I've had to settle for a Wyse WY-50 for my retro collection, which although is VT compatible, is not nearly as nice.

I've recently started writing a terminal emulator (because...) and it's surprising how many capabilities of even the vt10x's are not supported properly by most terminal emulators. Never mind the newer ones like the VT420 with ReGIS and Sixel support etc.
Terminals seems to have gone largely backwards in terms of capability. I guess largely because they're mostly used for the lowest common denominator, and beyond that people move to web/gui interfaces, and so little software requires a more capable terminal.
