I'm also from the old school, and I seem to remember a lot of people saying "wow! you have the new game genie....let me borrow it!"
I admit, hacking takes a lot of fun out of gaming, but if done properly, it can enhance the experience. You certainly have to have a bit of self-control because it is very easy to ruin a great game. It's best to hack AFTER you've thoroughly completed the game (if it can offer any additional fun).
That said, this isn't a game I particularly like, and the thought of playing it for even 10 minutes every day for the next 2 years kind of made me....sick to my stomach. I wanted to speed up whatever masochistic pleasure I was getting from this game.
I hacked Shuffle as well, and it has its pros and cons too. Pro: I can play at my own leisure: rather than pick the game up 5 times in one day to play 5 levels each time, I can just pick it up ONCE and play 25 levels. Cons: It's much easier to justify the use of a powerup to get it over with. Before hacking, I got pretty dang far without using a single power up (no grinding, no farming, just playing without spending.) However, this is not your normal "balanced" game: it is a money grabber. While it may be *possible* at this point not to use coins, it was turning into a fairly frustrating experience. With a normal game (aka a non-free to play game) you always know that no matter how difficult it is there is a way to beat it and with enough practice and attempts you WILL beat it. With this free-to-play crap, you're constantly suspicious that each difficult encounter was an intentional attempt to get you to buy your way through.
In the end, I'm glad I hacked both. They're just little free-to-play mediocore games anyway. I should be spending my time on higher quality games (that I won't ruin by hacking).
P.S. I'd like to know about these ways of catching the Pokemon your after. I found msyelf limited myself to mostly using only those with the Gutsy trait. I'd rather be able to ignore that trait and just use what I want, but the Gutsy trait helps SO much, especially my little Bisharp with a Gutsy++
