I was interested in the Kirby games too, and Squeak Squad was my first DS game — it was OK. It’s kind of rightly been forgotten by history because it’s pretty bland, especially among the other Kirby DS games, which range from great (Mass Attack) to excellent (Super Star Ultra).
But what really got me excited for the DS was Pocket Monsters Diamond and Pearl. Me and my friends had played all the Gen 3 games through to completion again and again, spinoffs included, and we followed Gen 4’s development closely. I remember logging onto Bulbapedia at like age 8, seeing the new starters, and just about losing my little head.
When I got the game, I was quite impressed! The DS Pokemon games had this kind of “sleek”, high-quality presentation to them that made ‘em feel really professional and well-made. Gen 4 isn’t really my favourite one, but I like a lot of it and it’s pretty nostalgic for me. (Through weird circumstances, I actually had both Diamond and Pearl.) We repeated our hype cycle when Platinum came out, and by the time of HG/SS I was active online with other people into the games, too, and got the chance to be somewhat involved in the culture. Good times!
