Ah yes, I've seen SWATH before. Here's my issue: when I started playing, it was on a BBS where everyone played manually. There were no helpers or scripts. We'd manually keep track of sectors and port pairs and potential bubbles and so on. It was great. I belong to the camp that believes the scripts ruined the game :-/
You don't have to use the helper bits of SWATH! Just turn that stuff off and enjoy it's near-perfect terminal emulation. I've played several games like that (these were old school 5000-sector games with rate limits, like how God intended you to play).
