Boarding before 0.6a, when the game was called Starfarer in most of those releases, was kind of fun, but too rewarding (pristine ships because no D-mods at the time). End result is reminiscent of modern ship recovery.
Boarding after 0.6a (but before ship recovery in 0.8a) was a frustrating random slot machine experience where the most reliable and riskiest option still only had about 37.5% chance of success on the ships that mattered (and less than 10% using the safe but expensive option), and you could only board one ship at the end of a fight. If you really wanted to capture a ship you really wanted, you could spend over an hour save-scumming and replaying that battle just to get that ship. (And later 0.7 releases had some anti-scum features, which meant you needed to save even earlier, about two to four in-game weeks before triggering that named bounty encounter, and wait longer before you can trigger than fight, extending the time per attempt.)
