Play Fossil League - Dino Tournament Championship (E) Online

Fossil League: Dino Tournament Championship came out for the Nintendo DS in 2007, published by D3Publisher. It was one of those mid-lifecycle DS games that didn't get a ton of attention but found its niche among players who liked creature battlers and the portable system's library of RPGs.

You control a young trainer traveling through time to collect fossils, revive dinosaurs, and enter them into turn-based battles. The main goal is to win the championship by defeating rival teams across different prehistoric eras. Signature mechanics include excavating fossils with the touch screen to build your roster, and managing each dinosaur's elemental affinity and move set to exploit type advantages. The pacing is methodical, with exploration and resource gathering between fights, and the difficulty can spike if your team isn't well balanced. It feels like a satisfying puzzle whenever your strategy pays off in a close match.
