User blog comment:H-Man Havoc/ME3 Recommendations (Everything except plot improvements)/@comment-743796-20100719230512

I like the hacking mini-games from ME2, as they are pretty simple to do. As much as I like the button-pressing from ME1, it get really boring after a while.

It would be interesting if you could pay (using skill points) to upgrade biotic abilities. This is how abilities are gained in other similar franchises, so I don't see why it shouldn't be done in ME3.
