Worst case scenario in the game is ~1.5% of the population. The estimated fatality rate is 0.5%. This number is increased to 1% if the hospitals are overwhelmed (note that there was a strong consensus in the country that this needs to be avoided).
Note that only 1/4 of the infections get detected in the game the game so the ratio deaths/detected infections will be 4% (the deaths/actual infections is 1%) - likely too optimistic in the scenario of overwhelmed testing capacity.
If you do nothing in the game, you kill 1% of the population during the first wave and you kill another ~0.5% in winter after the natural immunity of some people expires. Again, the real country was simply not willing to go that far.
