I recently bought the game LISA on Steam, and the humor approach is fascinating. Unfortunately, this approach involves being incredible vague, or outright obtuse, at telling you what is going on, or what is going to happen if you do something. The very first choice you have in the game is whether to choose “Pain” mode or “Normal” mode. It doesn’t tell you anything beyond that. Unfortunately, I interpreted this as “Normal” and “Easy”, and so I chose the former “Pain” mode. One of the “features” of pain mode is that you can only use save points once, and there are only 36 of them in the game, spread very far apart. After I was a few hours into the game, and I realized how much of a bother this was going to be, especially because it meant I had to play in possible multi-hour chunks, not knowing when I would get to stop. I didn’t feel like replaying up until that point, so I decided to do some save game file hacking, as that is part of the fun for me.
DO NOTE, this method involves deleting some of the data in the game file, specifically a bunch of boolean flags, which might cause some events in the save to be “forgotten”, so they will reoccur. At the point of the game I was at, the few deleted flag actions that I encountered didn’t affect anything big or of importance. One example of this is the long-winded character repeats his final soliloquy when you enter his map.
