There are a lot of exciting games to play in base alone, to the point where other members of the forum will probably confuse you for a troll.
Some people have trolled saying this...
There have been a lot of people who think this, but it's not the case. There are basically four stages to learning Dominion strategy:
1. The noob stage, where people make mistakes and buy random action cards.
2. The Big Money stage, where people think the best strategy is buying just money and victory cards (and maybe one or two kingdom cards). This is where you are.
3. The "intermediate" stage, where you realize some kingdom cards can compliment big money, or especially each other.
4. The "expert" stage, where you start utilizing kingdom cards in the best way possible and start building amazing decks such as engines, combo decks, etc.
Most people are in either stage 1 or 4 (4 has a
very wide range of skill). Reading the articles on the main site can help you through the stages a lot.
