Why can't it be? Factorio death is pretty simple. You drop your loot and corpse run to pick it up. It's not a huge setback. The only time it becomes an issue is when the player builds far away from spawn. There's no way to change the spawn location so a far flung base becomes its own kind of risk. That's not very important to this discussion though.Since when is the puzzle's punishment death?
Then maybe the problem exists between the user and keyboard? There ARE solutions to making the train network safer. There ARE ways to avoid getting run over. The most effective way that works 100% of the time is to not stand on train tracks. Should biters stop biting me because I don't like to shoot them? No. Trains shouldn't stop being trains just because you're racing for the Darwin awards.I just bring this up, as others were pissed of by my train network
This idea only creates more issues than it solves. Why can trains run over biters but not players? Why can tanks run over some things but not others? What if a player just wants to grief your train network by standing on the tracks? No. It's a dumb idea. You need to learn to stop attacking people who tell you that bad ideas are bad. If you can't even find the issues that your idea generates, never mind find ways to overcome them, then act like the trains you dream about and stop.
