I get the impression the vote would go something like:

Initial scores = 0

Round 1

Mars: 45% +0 = 45 (-50 = -5)
Venus: 55% +0 = 55 (-50 = +5)

Round 2
Mars: 45% -5 = 40 (-50 = -10)
Venus: 55% +5 = 60 (-50 = +10)

Round 3
Mars: 45% -10= 35 (-50 = -15)
Venus: 55% +10= 65 (-50 = +15)

Round 4
Mars: 45% -15= 30 (-50 = -15)
Venus: 55% +15= 70 (-50 = +15)

Venus wins as >2/3

This means that a majority can get anything past if they stick to their
guns, however, it will take lots of votes (spaced say 1 day apart).

It also naturally scales the time spent debating based on how
controversial the decision is.

Handling multiple choices could be handled with approval voting. Using
multiple rounds means that the tactics for approval are easier to use.

For example, if you could use the following formula

New Approval = 2/3 * ( Old Approval*3/4 + approval from vote )

if 50% approve of an option, it will get

Round 1:
2/3*( 0 + 50) = 33%

Round 2:
2/3*(25+50) = 50%

Round 3:
2/3*(38+50) = 59%

Round 4:

2/3*(44+50) = 63

At round N (with N -> inf)

Round N

2/3*(50+50) = 66 and 2/3

Round N+1

2/3*(50+50) = 66 and 2/3

I would suggest rounding upwards to the nearest percent. Ignoring rounding
an option cannot get the supermajority unless it has 50%+ approval.

Alternatively, rounding down could be used and the supermajority could be
set to say 65% required.
