1. Way too many to list, sorry.
- Phobia: the final level is extremely unfair, and the final boss unbeatable
- Operation Stealth: these annoying arcade scenes got me to quit trying
- Druid 2: I reached the baddies tower, but it just got too hard for me there
- It Came From the Desert: I couldn't survive in the ants' nest so far
3. Every game in the whole universe
