Germany pretty much always has coalition governments. We have 5-6 parties in parliament regularly. We have general blocs, though alliances might shift on topics, but generally you had the somewhat-far-left party, the social democrats and the greens being allied, and the then conservative CDU/CSU (now conservative-leaning centrist) and the financially conservative, socially liberal FDP on the other side. You'd still have coalitions, e.g. right now it's CDU + SPD (social democrats), but the (published) split is there as much as it ever was. It's changing now, as a new conservative/far-right party has emerged, and the green party gets lots of love from the media and has won some state elections (on a conservative platform, ironically), so it's hard to say where we'll go from here. I don't think more parties necessarily break it up. During the cold war, we had a Soviet bloc and a Western bloc, even though you had individual countries in each.
