I am a complete beginner. I have played some games on slippi with a keyboard(thats the only controller i have ) and it was quite fun. However, my keyboard isnt that good for gaming (ghosting issues, uncomfortable size, etc.) Other than my PC, i don't have that much gaming stuff. What do I need to buy? I live in lithuania so I can't buy GameCube controllers without big shipping fees
