I run a MUD and play several. MUDs by definition have only line-based
input (if you use a raw TELNET client, you have character-based input,
but most MUD clients send entire lines of text at once); yet it is
possible to implement a reasonably-viable file editor. It's not
difficult to become quite proficient with line-based editors,
especially if you rig some client-side support (which I have done on
two of the MUDs).

Line-based input is excellent as a command interface, if commands
consist of verbs and parameters. It's terrible for playing Tetris on.
