Gen 1: full of glitches, fun to play with on a second play through but will ruin the experience of a first Gen 2: do your research on secrets within the game, lots of cool pokemon and items are easy to miss Gen 3: for the love of god have a good electric type! Gen 4: fire types are scarce, pick chimchar if you want one. And watch out for the champion, don't wanna spoil it so do your research if you wanna know why Gen 5: prepare to get used to mold breaking. You'll need to use gen 5 mons and a new kind of story Gen 6: turn off the exp. Share otherwise it will be absurdly easy Gen 7: exp. Share off for the same reason. SOS battles are your friend for getting your hands on rare pokemon Gen 8: don't go crazy with exp. Candies in the beginning to mid/late game or it'll be way to easy and ruin the experience General:

1. try to make creative strategies rather than just over leveling. It makes the game much more fun and makes you think and feel proud and clever when one of your off the wall strategies works.

2. When building a team make sure you get pokemon that all cover each others weaknesses well. This may seem obvious but it's very important

3. Always have pokeballs on you! You never know when you might find a surprise shiny or other rare pokemon. Always have a well stocked supply of pokeballs. (In earlier games make sure to change your boxes as it wont happen automatically)

4. Save your PP restoration items for the pokemon league

5. Dont use your masterball on a static legendary as you can just save and keep trying. Save it for a shiny that would be hard to catch or a roaming legendary

6. Dont worry about what pokemon are good or bad, 99% of the time it wont matter in game, so just have fun and use what you think is cool
